9 Best Allen Wrench Set Reviews in 2022


Allen or hex fasteners are something that you simply can’t avoid when it comes to official workshop jobs or even DIY projects that you are getting done in your backyard. And these fasteners can only be operated with the help of an Allen wrench of a suitable size.

Therefore, keeping a complete set of Allen wrenches in your toolbox is definitely a crucial part of having an all-inclusive tool and accessory set. With a full set of Allen wrench, you can easily tackle a wide range of hex screws, bolts, or any other Allen fasteners. Since Allen wrench sets are similar to any other type of tool set, you should consider some basic parameters mentioned below to get the best option for the job.

  • Material: The base material used for manufacturing a tool affects its overall strength and capability to perform a job. So if an Allen wrench set is made of a rather brittle material, its applications will be severely narrowed down to basic jobs and you will have to be really careful while using such Allen wrenches. Instead, if you are going with an option that is made up of carbon steel, alloy steel, or vanadium steel, you will get a much longer lifespan and high strength with these tools.
  • Size: Just like any other tool, the compatibility of an Allen wrench set depends upon the sizes of Allen wrenches included in the unit. If the one Allen wrench that you need is not available in the set, the entire set won’t be of any use to you for that particular application. And unlike screwdrivers where you can get past the compatibility problem with one size lower, Allen wrenches have to be exactly the same as the hex nut you are going to fasten or loosen with it. Therefore, make sure you check the available sizes in the set before making a choice.
  • Storage: If you already have a lot of tools and accessories spread across your tool collection, adding a bunch of Allen wrenches to the mess won’t be ideal as it will simply make it even more difficult to find the right tool for the job. Instead, you should consider going with a set that comes with a dedicated storage unit that can contain all the Allen wrenches in a safe and secure position. All of the options available on our list today offer some kind of storage solution for the Allen wrenches included in the set.

Now that you know what factors make up a good Allen wrench set, let us dive into the best Allen wrench sets available in the market right now. We have carefully shortlisted these options on the basis of the factors mentioned above and some more important qualities. Therefore, you will surely find a couple of great choices for your job on our list today. If you need help while picking up a set, simply refer to our Buying Guide for the best Allen wrench set presented right after our picks to get a better idea.

Buying Guide For The Best Allen Wrench Set

Whether you are a beginner in the field of craftsmanship or an experienced professional, you will definitely find yourself needing a decent set of Allen wrench sooner or later. Since a lot of products these days are secured with the help of hex nuts and fasteners, it is crucial to have an Allen wrench set around if you ever need to disassemble these products for repairs or part-replacements. And for that reason, almost all DIY home tool kits include a specific set of Allen wrenches. In case you have missed out on having one in your tool set, don’t worry.

We have brought a great selection of Allen wrench sets present in the market right now that you can get right away and complete your arsenal of tools and accessories. However, you should consider the fact that not all Allen wrench sets are the same and each option is suitable for a certain set of applications. And to help you find the best option for your needs, we are bringing this helpful buying guide for the best Allen wrench set.

1. Material

The base material used for the construction of a tool becomes one of its most important factors since the overall strength and applicability of the tool are highly dependent upon it. If the tool does not incorporate enough strength for the job, it will simply break once you apply a little excessive pressure. Therefore, the tool or tool set you are buying must have strong construction and it should be made up of materials like carbon steel, chrome vanadium steel, alloy steel, etc.

The basic rule in every case is that the tool is supposed to be harder and tougher than the job. If this rule is satisfied, you can easily use the tool for all types of applications without worrying. Another important parameter that comes into play here is the coating provided on top of the base material to avoid problems like corrosion and rusting. A lot of brands go with nickel or black oxide to prevent environmental effects on the tools, which works out fine in most cases.

2. Chamfered vs Non-chamfered Allen Wrenches

If you take a close look at an Allen wrench, you will notice that it is a pretty simple tool in terms of design and construction. It is nothing but a metallic bar of the hexagonal cross-section with a bend at the front, and that’s it. But, there are small improvements that are introduced by a handful of brands that make the tool more durable and increase its expected lifespan by a significant margin. For example, some brands increase the quality of the Allen wrench by introducing a chamfer at the end of the tool.

While it may not look like much of a difference in terms of design, it certainly increases the ergonomics of the tool. If you are using a chamfered Allen wrench, you can locate the wrench even more quickly and it will be safe from accidental damage caused to the edges of the tool. Some Allen wrenches have a ball-end which offers even more benefits. Such designs allow you to apply more pressure on the tool at an angle to allow operation on rusted or frozen hex nuts.

3. Length of the Tool

As we all know the basics, the amount of force needed for a job decreases along with an increase in the distance from which you are applying it. This basic rule fits perfectly with Allen wrenches as you are not going to apply the force directly on the end of the Allen wrench. Instead, you will be rotating the handle of the Allen wrench which will generate a moment of force at that particular point.

As you might have guessed already, the moment of the force generated at the connecting point of the tool increases with the increase in the length of the handle. To make that happen, Allen wrenches are usually made with 1 to 4 inches long handles. But, if you find an overly long Allen wrench, you should consider other options since these options are not the best choices for operating in compact spaces. Also, the handle of the Allen wrench needs to be ergonomically accurate to offer a comfortable grip to the user.

4. SAE and Metric Systems

All tools and accessories designed in the USA are mostly calibrated with SAE or imperial measurement systems. On the other hand, imported goods from places like Europe or Asia are designed with a metric system. While general conversion of these measurement systems allows you to easily switch between the systems while you are working on certain jobs, it is not that simple when it comes to tools and accessories. Even a small difference in the fastener size caused by SAE and Metric units can make the tool useless for the job.

And as you may already know, forcefully using the tool for the job causes nothing but damage to the workpiece or the tool itself. Therefore, you should carefully consider what type of measurement system you deal with on a regular basis and pick up an Allen wrench that is designed with the same. And if you want a versatile choice, go with the set that includes both SAE as well as metric wrenches to make all types of applications possible. And with the sets that cover both SAE and Metric sizes, you will find more wrenches per set compared to those that are suited for only one type of measurement system.

FAQs

Q. Are hex keys and Allen wrenches similar?

Hex keys and Allen wrenches are not just similar, but they are the exact same thing with 2 different names. Hex keys and hexagonal nut screws were first invented by the Allen manufacturing company which names the units “Allen wrench”. In the USA, these units are called Allen wrenches whereas, in Britain, they are called Allen keys or hex keys. So, whether you are looking at a set that contains hex keys, Allen keys, hex wrenches, or Allen wrenches, it is simply the same set of tools with different nomenclature.

Q. How to use an Allen wrench?

Allen wrenches are pretty straightforward tools and using these tools is not that different from using a screwdriver or a regular wrench. First of all, you need to insert the hexagonal end of the tool into the hexagonal slot available on top of a hex nut or screw. Then, you simply turn the tool clockwise or anticlockwise to tighten or loosen the nut respectively. The force required to do the job depends upon the type of Allen wrench you are using. With a T-handle Allen wrench, you can apply a greater force whereas a ball-ended wrench lets you use the tool at a difficult angle.

Q. Where will I need an Allen wrench set?

If you are not sure whether you actually need an Allen wrench set or not, you might be wondering about the applications of this tool set. In any case, you should still get a versatile set of Allen wrench since it is better to have the set and not need it, rather than needing it and not having it. Here are some common applications that usually require an Allen wrench set.

  • Furniture jobs, especially tables and stools
  • Opening up power tools
  • Accessing the internal arts of monitors, TVs, or other similar accessories
  • Working on automobile accessories
  • Plumbing jobs

Conclusion
