How to Choose The Best Allen Wrench Set

While Allen wrenches are made to get the job done at ease, the right Allen wrenches will give you the best results and more efficiently. We have gathered all the information about Allen wrenches to offer you this buyer’s guide so you can be equipped with tips on getting the best deal for your purchase. 

Here are some features you should pay attention to while shopping to get the best Allen wrench set. 


The best Allen wrench set will come with the most durable material. You will need to look for those materials like high-grade or heat-treated steel, or chrome-vanadium metal. Anything that is durable and not brittle. 

Before you decide on any Allen wrench set, look up the reviews of that specific set. Make sure you pay attention to those reviews especially of those smaller size wrenches, as they are usually the most fragile ones. 

Besides, you should also definitely check on the coating of those Allen wrenches. Most of the highly-rated sets are often coated by a black-oxide finish to avoid it from rust and corrosion. The coat will help prolong the keys’ life, helping you to keep the tool for many years of service. 

Number of wrenches

Depends on the type of job you’re working on, or your professional level, the number of Allen wrenches will be different. 

If you’re just working on electronic or around-the-house jobs,  you don’t necessarily need to own so many wrench sizes. However, if you work in a wide range of maintenance jobs, it’s ideal to get yourself a set with a variety of wrenches. 

Measuring systems

The two most common measuring systems available for Allen wrenches in the market are SAE or Metric. SAE is also known as imperial, or for you to understand, it’s inches. 

An Allen wrench set manufactured from outside of the US usually marked with metric units, instead of SAE. Users might need to buy for another different set of SAE wrenches. 

Thus, try to get yourself a set that includes both of the measuring systems. They come as 2 separate packs, one for SAE and one for metric units. 

Chamfered or Non-Chamfered Edges

Recently, some Allen wrench sets in the market feature chamfered hex keys

Unlike the normal ones, Chamfered Allen wrenches are designed to be slightly rounded at the end. This allows the wrench to easily slide into those hard-to-reach and blind slots. It also lessens the chance of damaging screws or bolts while being inserted or removed out of the tools. 

Another level of chamfered Allen wrenches is ball-ends. This kind of wrench end allows users to slide into a screw from many different angles, offering the flexibility everyone loves. However, it poses more potential to slip under pressure more than any other type. 

On the other side, non-chamfered Allen wrenches have square ends, making them more likely to damage weak screws. However, for the same square end, this type of wrench is able to deliver much more rotational power than the above-mentioned. It’s hard to slide into slots but once it’s in, it gives users the best tool to tighten and loosen bolts.


The longer the Allen wrench is, the more useful and powerful it becomes. Long Allen wrenches can reach deep narrow places, which is impossible for shorter wrenches. In other cases, the biggest advantage of long Allen wrenches is that users will produce more force, helping you get the job done much more efficiently and faster.  

Storage case

Don’t overlook the storage case. The best Allen wrench set sometimes comes with the best storage case, although this isn’t applied for all. However, having a case will do you more benefits than you think. 

Your set will be securely stored, no matter it is a folding case or a hinged one. You will have an easy time identifying and picking out the desired wrench.
