#2. Sargent & Greenleaf S&G Environmental Padlock


We’ll end this list with another great outdoor lock – the Sargent & Greenleaf S&G Environmental Padlock 9/16″. Just like the previous padlock we took a gander at, this Environmental Padlock also comes in two different sizes.

Depending on the application, you can choose between a bigger and a smaller shackle. But whichever one you opt for, in our experience, you can definitely be sure that this Sargent & Greenleaf model will protect whatever outdoor facilities you need it to.

Pros:

  • Innovative design
  • High tensile resistance
  • Rust-resistant

#3. Abloy PL 342T PROTEC2 Shrouded High Security Steel Padlock


Seeing as Abloy is one of the most well-known padlock manufacturers out there, you shouldn’t be surprised that they’ve got more than just the top-grade stuff to offer you. After all, padlocks aren’t just for people who have maximum-security needs.

If you’re willing to invest some money into a quality padlock, but don’t want to burn through your home security budget – the PROTEC2 Shrouded High Security Steel Padlock is the thing you’re looking for.

Unlike our previous pick, this one is Grade 4 instead of Grade 6. However, it too can boast with a sturdy steel body, along with shackles made out of hardened boron steel and raised shoulders. It too will resist most attempts of drilling or cutting it open.

Features: Most Secure Door Locks

  • Grade 4
  • Best outdoor padlock weatherproof
  • A chrome finish on a body made out of case-hardened steel
  • Hardened boron steel used to make the shackles, also with a chrome finish
  • 11 Discs

As you’ve probably gathered by now, this padlock is designed to be the mid-range counterpart to the previously reviewed top-tier Abloy padlock. And while it can still boast with high production qualities, it’s visibly cheaper than its more costly cousin. However, if you need it for something like an ammunition locker around the house, it will more than get the job done.

Pros:

  • Hardened steel
  • Production quality you’d expect from Abloy
  • Lower cost

Cons:

  • Lower production quality compared to Abloy Protec2 PL 362

#4. Medeco M3 Shrouded Padlock


Medeco is a well-regarder manufacturer of high-security locks. What’s interesting about the Medeco M3 5/16″ padlock is the amount of choice you’ve got once you decide to buy it.

You’ve got two different body styles to choose from; one that’s more resistant to weather for outdoor use, or one with a shrouded shackle that provides additional protection against cutting.

Though, both of the models do have a shackle made out of boron steel, making it pretty impervious to cutting on its own. It’s tensile strength is also pretty impressive, making it tough to pull open as well.

Features: Most secure door locks

  • Boron steel shackle
  • Stainless steel body
  • Medeco cylinder
  • Two different variants

This lock also boasts a patented keying program that makes unwanted key duplication pretty much impossible. And the Medeco3 design is designed to render the lock basically impervious to picking by thieves.

If you want to duplicate a key, though, you’ll have to go to a sales outlet authorized by Medeco. That hassle is well worth the price of additional security, as no-one but the owner of the lock can make a key duplicate.

Pros:

  • Code card preventing unwanted key duplication
  • Quality shrouded shackle
  • Pick-proof

Cons:

  • Hassle to re-key or duplicate keys

#5. Abloy Protec2 PL 330 Padlock


Naturally, not all of us have the same needs when it comes to home security, or security in general. That’s why even a 180-dollar padlock like the Abloy PL 342T may be overkill for you. And bearing that in mind, we’re going to take a look at another, lower-tier lock made by the people at Abloy.

The Abloy Protec2 PL 330 is pretty much your regular, run of the mill padlock; it won’t surprise you, but it won’t disappoint either. It’s smaller, with a medium body, but also a shackle that’s far from easy to cut.

Features: 

  • Abloy Protec2 rotating disc technology
  • Master key System
  • Brass body
  • Hardened steel shackle

When you compare this lock to the ones above made by the same manufacturer, you’ll see that it’s precision oriented production still holds up. The Master key system is also a great simplifier of key management, and you’ll also find this padlock holding up in extreme weather conditions.

That means you can expect it to remain useful and sturdy even if used for a storage unit kept in icy temperatures, for example.

Pros:

  • Reliability in extreme climates
  • Affordable price
  • Easy key management

Cons:

  • Less sturdy brass body

#6. ABUS Granit Padlock 37/80 Alloy Steel


When it comes to this lock, you may think that we’re just repeating ourselves. But actually, not – while the ABUS Granit padlock 37/80 is quite similar to the previously described offering from the ABUS Granit series, it’s actually got two distinct differences, which we’ll get into.

Features:

  • 5 tons of tensile resistance
  • Hardened body measuring 65 on the Rockwell scale
  • Optimal pull and drill resistance
  • Bottom plate made out of hardened steel

Compared to the previous lock we’ve mentioned, this ABUS padlock has a much wider shackle, as well as almost twice the tensile resistance. So, if you feel that the previous iteration just isn’t enough for you for some reason; this will definitely do the trick. Let’s just say that you won’t find any bolt cutters capable of going through this.

Pros:

  • More tensile resistance
  • Pretty much safe from physical harm

Cons:

  • Bigger price
  • Wider shackle may not fit every chain

#7. ABUS 37/60 Granit Alloy Steel Padlock


In the world of high-stakes security, sometimes you truly have to pull out all the stops. And if you purchase a set of ABUS Granit Padlocks, you’ll truly be doing just that. Generally, these locks are viewed as some of the safest padlocks in the entire world; with a tensile resistance well over 6 tons.

These German-produced padlocks are made from premium-quality materials, and they’re laced with studious finishing. They’re made unique by their luminous, easy-to-find keys and their pitch-black coating made out of granite.

Features

  • German-made
  • Hardened steel body with granite coating
  • Hardened steel shackles
  • 2 keys for each lock
  • ABUS disc cylinder
  • Corrosion resistance

Interestingly enough, all locks from the Granit series can also be purchased as a SZP version. That means that you’ll get a security card along with your lock, which will exclusively contain information on how you’d go about making further key copies. Importantly enough, the only way a locksmith can make more key copies is if they have this security card; making sure that the owner controls how many keys will be made.

Pros:

  • Resistant to corrosion
  • Additional security card
  • Quality granite coating

Cons:

  • Heftier price than other ABUS locks

#8. Abloy Padlock PL 330


Before we finish our review segment on Abloy products, we’ll take one final look at one of their locks: the classic Abloy Padlock PL 330. There’s a reason why this is called a classic, as Abloy is actually a company with a long and proud history.

The Abloy Classic cylinder system which the company has patented is in production all the way since the 1920s. Their unique rotating disc cylinder structure provides for extreme security even in their simplest models, without any pins and springs.

Features:

  • 25mm Steel Shackle –
  • 2 Keys
  • Brass Body

Essentially, this is pretty much a standard bike lock that you’d use for a bicycle, or the doors on a smaller truck. It’s a cheap, no fuss lock that’s the most standard item you’ll find on the market.

Pros:

  • Abloy Classic cylinder mechanism
  • Durability
  • No pins or springs

Cons:

  • Brass body prone to drilling
  • Durable for its price range, but not meant for extremely serious security.

#9. ABUS 20/80 Diskus Stainless Steel Padlock


Our next pick of the draft comes imported from Germany: the ABUS 20/80 Diskus Stainless Steel Padlock. This disc-shaped padlock is pretty unique, and it’s got a couple of advantages that make it a safer bet compared to the competition.

First of all, its disc shape means that it’s extremely resistant to bolt cutting; the jaws of the cutters can’t even get around it. And its stainless steel casing means that it won’t corrode either. You can also choose different sizes, depending on your needs.

Features:

  • ABUS Disk Cylinder
  • Stainless steel body
  • European-grade padlock

If you want an imported padlock for a small price, this ABUS is one of your best choices available. The disk cylinder is designed to combat any manipulation; though it can still be tampered with via prolonged drilling.

Pros:

  • Plenty of key differs
  • Completely protected against bolt cutters
  • Safe from corrosion

Cons:

  • Susceptible to drilling

#10. ABUS 83CS/55-300 S2 Schlage 55mm Rekeyable Padlock


Here’s another fine product from ABUS, representing the pinnacle of German padlock engineering. This padlock is designed for the easiest possible rekeying, saving you plenty of valuable time by rendering this process simpler than ever.

There are no unneeded variants for key retaining or different shackle lengths. Also, you’ve got the corrosion resistance that ABUS is pretty much famous for.

Features:

  • Corrosion-resistant plating
  • Quick rekeying
  • Prompt shackle changing
  • Hardened steel body

There are no two ways about it; this is definitely a heavy-duty security lock, made out of fine-quality steel. However, there’s just one nitpick about it that we think you should be aware of.

Once you receive the lock, you’ll have to bring it to a locksmith in your area, in order for them to key it. You’ll get one blank key with the lock for that; but the whole process adds at least $20 to the price of the item.

Pros:

  • Easily rekeyable
  • Sturdy body and shackles

Cons:

  • Hidden additional cost of having a locksmith key it from the start

#11. Master ProSeries 6327


Next up, we’ve got a budget friendly lock that should definitely take care of your everyday needs. The Master ProSeries 6327 is a no-fuss paddle lock that’s designed to protect the shackle as much as possible. Price is under $50, it does the job well enough.

Features:

  • Boron hardened steel shackle
  • Steel Body
  • Weather Resistant
  • High Security
  • Rectangular Shape
  • Rekeyable

Let’s get something out of the way; this lock won’t exactly stop a pro lock picker. But if you’re dealing with a novice crook who wants to break into your shed, this is more than adequate. The truth is, only the most determined thieves will actually try to drill through a padlock; that sort of thing makes for a lot of noise.

And if you’re afraid of that, you’ll need to buy a $200-priced padlock, some of which we’ve mentioned on this list. But, if you’re looking for something to slow the crooks down; this is great. So, good for your bike, but not for an expensive motorcycle.

Pros:

  • Rekeyable lock
  • Bigger than most price-range competitors
  • Resistant to bad weather

Cons:

  • Not that resistant to drilling or cutting

#12. MasterLock 6230KA Solid steel


Next up, we’ve got another lock from MasterLock, but this time it’s a sturdier, commercial-grade item. It’s got quite a heavy casing, meaning that it’s pretty resistant to drilling – and the body is made out of steel. Also, the shrouded shackles provide excellent protection against possible bolt cutters. And all of it is covered with a chrome film, giving it protection against rust and thus a longer lifespan.

Features:

  • Body made out of hardened steel
  • Boron hardened steel shackles
  • Best cheap padlock
  • Chrome rustproofing
  • Keyed Alike
  • Weather Resistant

Compared to the previous padlock from MasterLock, this one is definitely a better security measure. Though, it’s average price tag means it leaves the confines of the lower tiers and jumps into the mid-tier section of our padlock reviews.

So, if you’re looking to use this for gym lockers or something else requiring a multitude of items; you’d be better off with something cheaper.

Pros:

  • Resistant to extreme weather
  • Steel body protecting against drilling
  • Protected against rust
  • Best padlock for gym

Cons:

  • Pricey for a mid-range lock
  • Not cost-effective when an entire series of them is needed.

#13. ABUS 20/70 Diskus Stainless Steel Padlock


The final ABUS product we take a look at will, symbolically, be the simplest one. In many ways, this padlock model is where it all began for the company. This type of padlock has been crafted in Germany ever since the end of the 1940s, with only premium-quality materials.

Features:

  • Handcrafted in Germany
  • Best cheap padlock
  • Stainless steel body and finish
  • Diskus Deep Welding for best possible strength
  • ABUS disk cylinder technology

This lock is pretty much the most basic disk-shaped product you’ll find from ABUS, costing only around 30 bucks. While it’s advanced enough for basic home security it has only one drawback; making new keys isn’t easy, as they have to arrive from Germany; each shipment taking a couple of weeks.

Pros:

  • Advanced anti-drilling and anti-cutting security
  • Made out of top-notch raw materials

Cons:

  • Making new keys is quite the hassle

#14. American Lock A5360 2″ (51mm) Shrouded Solid Steel


The final padlock we’ll take a look at in our best bolt cutter proof padlocks review is the American Lock A5360. This padlock is a simple, no-hassle one, albeit with a somewhat awkwardly shaped shackle shroud. It’s pretty resistant to any kind of prying and pulling, and the 6-pin rekeyable cylinder makes it almost impossible for lock pickers to crack.

Features:

  • Solid steel body with chrome plating
  • Best padlock for gym
  • Shrouded shackle made out of boron steel.
  • Rekeyable cylinder

The only real downside of this lock is it’s somewhat narrow shrouded shackle, making it a close fit on many thicker chains and door handles. However, for this price that’s definitely not too much of a problem.

Pros:

  • Affordable price
  • Great quality steel
  • Impervious to lockpicking or cutting

Cons:

  • Narrow shackles

Which Features To Check When Buying Padlocks


Padlocks come in a wide range of security levels, but there are three key features that determine the safety of a padlock. Since picking the right padlock can prove to be a great investment, or a costly mistake; lets skim over the top components you should take into consideration.

  • The Body.
  • The Shackle.
  • The Locking Mechanism.

The quality of these three components and how they work together is basically what determines the overall security. In the following text we will provide a detailed guide of how these mechanisms function.


How To Choose A Best Padlock – Locks That Cannot Be Cut With Bolt Cutters


When it comes to overall security, many manufacturers provide a ‘’Security Rating’’ guide. This guide informs the buyer about the security level of a padlock he wishes to purchase. However, if you are looking for an industry standard rating, there are two reliable guides which can come in handy, ‘’CEN’’ and ‘’Sold Secure’’.

The first one is an European standard and is categorised with numbers ( from CEN 3 to CEN 6). It is pretty straightforward- the bigger the number is, the higher protection level is assured. When it comes to Sold Secure, they have a different rating system; which consists of three categories- Bronze, Silver and Gold.

Regardless if you want an industrial rating to assure your security, or are looking for something less advanced, it is still handy to know what makes a lock safe.As we mentioned, one of the first characteristics you should take into consideration is the type of a padlock.  Padlocks usually fall into one of four categories, based on their shape.

1. Types of PadLocks

Shutter-lock/Anvil lock are generally used to secure motorcycle chains or parking posts, as well as the shop fronts.Discus locks are often used for securing entrance- on shed doors and beach huts. They  are usually used with a special discus hasp and staple set, to offer extra protection.

Even though the name implies otherwise, shackless padlocks still have a shackle, just on the underside of the lock.

They come in many shapes, but are typically designed to be used easier with a security hasp. Shackless padlocks are one of the more secure options, when it comes to general padlock types; they were traditionally used to secure warehouse doors, but nowadays people don’t hesitate to use them on a broader scale.

Conventional lock have undoubtedly the widest range of usage. They can be used for something simple like a tool box, but can also be found securing factory gates.

2. Different Materials of Padlock

Since we’ve covered the four main types of padlocks, it’s time to go through the materials and types of padlock bodies. The purpose of the body is to protect the lock mechanism from attacks. The usual body types you will come across are Solid Steel Alloy, Pressed Steel, Laminated Steel, Solid Brass and Armour Encased Brass.

With Solid Steel Alloy the internal cavities within the lock body need to be machined out. Compared to brass, steel alloy is a much harder material, so the machining operation takes longer- and to put it simple, they cost more. The body of this padlock is very robust and will make a drill attack near impossible They also come with a special feature that prevents them from rusting. Since they are usually a bit pricey, you will want them to last and this feature ensures just that.

Pressed steel locks are usually associated with a discus style lock. They are made from from double stainless steel shells welded together. These types of locks can offer a decent level of security for general usage, mostly because pressed steel locks are secured in the locked position at two points.

Laminated steel padlocks are made from numerous pre-punched steel plates that are welded together to form the body block. However they tend to have lower manufacturing cost, and as the end result have some weak points; for example, the exposed rivet heads. Depending on what you wish to secure, you may find them to be just the thing you need; but if you are in need of advanced protection, we would advise something else.

Since we are talking about cheaper options, Solid brass is also a good example of that. Brass is quick to make, and is relatively soft, which results in budget friendly prices. Although it comes at low cost, it is susceptible to high risk attacks, such as a drill attack. If you don’t want to spend a lot of money on a padlock and still feel completely safe, you can always buy an additional feature. In this case look no further than Armor Encased- a steel jacket made to increase security of a simple brass padlock! It provides an additional security measure that can always come in handy.

3. Shackles of Padlock

Another element of security is the shackle of a padlock. More often than not, this is the prime attack point. Most padlocks have a good mechanism that provides security at two places within the body, when your padlock is locked.

There are some differences to shackles, and they usually come as open, closed and semi enclosed. A closed shackle padlock is designed to have the minimum amount of shackle exposed; which means that if a criminal wants to saw it off, they will have a hard time doing so!

This type of a shackle typically has a higher security rating compared to an open or semi enclosed shackle. Although they may provide higher protection, they can be somewhat impractical to use. For making them more user friendly, some manufacturers include ‘’removable shackles’’ feature that allows you to fully release shackles from the body of the padlock.

Compared to a closed shackle, an open shackle padlock is much more easier to use; especially if you need your shackle to pass through chain links. Even though you will have no problem securing gate with a chain with this shackle type; you might be more vulnerable to potential attacks-  since an open padlock has more of the shackle left exposed.

Depending on what you need to secure, a semi enclosed shackle might be the best option. It is usually seen as a compromise between two previously mentioned shackle types – it offers improved security but also a higher amount of flexibility compared to a closed shackle padlock.

When it comes to the length of a shackle, many open shackle locks come with interchangeable lengths options. If your shackle needs to pass through multiple fittings, this can prove to be a good choice; but bear in mind that the more a shackle is exposed, the more vulnerable it will be.

Attackers usually use a saw or bolt cutters, and the longer the shackle is – the easier it is to find a spot to make their attack on. And bearing all of this in mind, we’ll provide you with an overview of the finest bolt cutter proof padlocks that you can purchase online. Read on and enjoy!
