Best Hex Key Sets In 2021
The idea of a hex key, a small L-shaped tool designed to drive different sized screws and bolts with their heads imbedded with hexagonal sockets, was first conceived around the 1860s. Lack of manufacturing options stalled production until 1910, when the Allen Manufacturing Company developed a cold-forming technique and quickly registered the trademark name “Allen Wrench” to describe the company’s clever little tool. Soon after, competitors in America and Europe fell over themselves to bring copycat tools to market, which have generally been referred to as Hex Keys ever since. Now, they are everywhere and have quickly become indispensable tools for professional mechanics and DIY enthusiasts the world over. We have looked at dozens of these tools and have created a handy guide to help you choose the best hex key set for your particular needs.
The Best Hex Key Set
You need two things from your hex key set – reliability and a range of sizes. Tekton is probably the company best positioned to provide that with every set of hex keys they produce. They produce some of the highest-quality tools around, and they’re available for both tradespeople and the public. This 26-piece Tekton Hex Key Set has every size you will ever need. There are more comprehensive sets available, but most of the extra hex keys in those sets are specialist tools that you’ll never use.
The 26 hex keys are split into two sets of 13 – inches and millimeters. They come in two separate color-coded holders, so you can keep them in perfect order. This type of housing is better than the book-style of hex key holders, as it’s more secure and easier to select the right tool. They’re made from heat-treated chrome vanadium steel and have a black oxide finish to stop them from rusting or getting damaged. In short, this set of hex keys is super high-quality, comes with two great holders, and contains all of the common sizes you’re likely to need. Be sure to also take a look at some of the best breaker bars from our list.

Fashioned in the distinctive bright yellow synonymous with Stanley tools, this two-set inches and Metric hex wrench set provides the functionality and durability millions of customers have come to expect from a company with a proud 170-year history. Crafted with rubber inserts to help increase grip, each hex set features chamfered edges for easier entry of the key. Size markings are printed on each body to make them simple to identify when you need to grab the right key quickly and without fail. The SAE (or inches) keys are as follows: 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 3/16, 7/32, and ¼. The Metric keys come in these sizes: 1.5, 2, 2.5, 3, 4, 5, 6, and 8 mm.
Getting the maximum performance from the Stanley set depends on a few different things, perhaps none more important than common sense. First, use the right L-wrench. If the key you have selected is too small, select one larger until you have the right fit. Secondly, to loosen a fastener insert the wrench into the hexagonal cross-section of the bolt and turn it counterclockwise until it fully loosens. To tighten the fastener, do the opposite by turning it clockwise. Our handy guide to the best crowbars features more great products like this.

Serious bicyclists know that it is critical to carry the right tools to ensure they get from Point A to Point B in a certain time frame. A high-quality bike pump and CO2 inflator are obvious choices but do not dismiss another must-have – a hex key set. Thankfully, Pro Bike Tool makes one of the best hex key sets on the market, the appropriately named Allen Key Set. Made from shop quality S2 steel, this indispensable tool set includes the L-shaped wrenches you would most likely need to fix your bike: 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10 mm. Weighing in at just over 12 ounces, the toolset fits neatly into an included tool organizer when not in use.
Hex key sets are the number one tool used for size adjustments and bike repairs. If you have ever been broken down on the trail or along the side of the road, you know the importance of carrying the right tool, and this set fits the bill. The varying sizes and ball-end tips on the allen keyset long are ideal when you are trying to reach awkwardly located bolt heads. Best of all, either end of the tool can be used, allowing you to extend your reach if necessary and get as much torque as possible. This key set is manufactured to the standards Pro Bike Tool is known for and is further backed by a lifetime warranty against manufacturer defects.
Even though this may seem obvious, the Pro Bike set is so useful that you should not need other tools with it. For instance, because most L-wrenches are relatively small compared to other hand tools, you should never hit it with a hammer to create more force. You should never clamp vice grips on it to help create more torque, mostly because a hex key is designed with torque in mind and can do a good enough job on its own if you supply a bit of physical “oomph” when turning it one way or the other.
