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 a crucial part of having an all-inclusive tool and accessory set. With a full set of Allen wrenches, 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.
- Size Range: A quality set should encompass a wide array of sizes, from the smallest to the most commonly used hexagonal sockets. Seek sets that offer a comprehensive selection, usually spanning from 0.7mm to 10mm for metric sets and 1/16 inch to 3/8 inch for standard sets.
- Material Quality: Premium Allen wrenches are often crafted from hardened steel or alloy, guaranteeing strength and durability. Choosing wrenches with a robust coating, like black oxide or chrome plating, can bolster their longevity and resistance to corrosion.
- Storage Options: Opt for sets that include a convenient storage case or rack, enabling tidy organization and easy access to the wrenches. Some sets feature fold-out cases or compact organizers, ideal for both portable use and space-efficient storage in toolboxes or workshops.

Buying Guide For The Best Allen Wrench Set
When choosing an Allen wrench set, it’s important to pay attention to features that improve your work and accuracy. Allen wrenches, also called hex keys, are vital tools in many industries like car repair and furniture assembly. To pick the right set, think about these important features before buying.
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.
Frequently Asked Questions
Ans: 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.
Ans: 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.
Ans: 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
