What Is The Best Allen Key Set?
More Detailed Allen Key Set Reviews
Wera 950 SPKL/9 SM N SB Multicolour BlackLaser L-key set Review
Wera is one of Germany’s best-known hand tool manufacturers, and this Hex-Plus multicolour set is quite simply the best Allen key set we’ve ever reviewed. The quality of the steel and finish is outstanding, we don’t expect it to scratch or bend any time soon.
For a simple tool, the Wera BlackLaser L-key set has made some useful innovations to help you out during use. The colour-coded plastic sleeve makes for instant size recognition, and will let you know straight away if a hex key is missing. The sleeve acts as an extra bit of grip, and will even help your fingers out if the temperatures drop low.
The ball-ended sections are brilliant for turning hard-to-reach bolts on an angle, and their extra length translates to more torque for less effort. The best hex key innovation that Wera have developed is the star shaped end that really grips into bolts and avoids any slipping.
The carry clip is handy as well, it feels like tough plastic and should keep everything in this Wera Allen key set stored securely when not in use.
Draper 33894 Metric/ Imperial Combined Long Pattern Hex Key Set Review
This reliable combination of metric and imperial long pattern hex keys from Draper are probably the last set you’ll need on site.
We really liked the range of Allen key sizes available in this hex key kit. An imperial hex key set alongside a metric one means you’re ready for any eventuality, and can tackle almost any bolt that comes your way.
The solid plastic case is slim enough to fit into a shallow tool drawer or bag, and keeps the allen wrenches organised for quick access when not in use.
Silverline 323710 Hex Key T-Handle Set 2-10 mm – 10 Pieces Review
Silverline are a well-known UK tool brand with plenty of experience making useful hand tools. Their T handle set of Allen keys is perfect for when you need to apply extra torque to a bolt.
The solid plastic handles fit well in the hand, and the Allen keys we tested out were comfortable to use and were surprisingly long, with the longest key at 24 cm. You have two options with each hex key, either the long shank for tight spots, or the stubby end for when you need that extra bit of power.
The best T handle Allen key set needs a robust stand, so we were pleased with the included one. It can be bolted to a wall or workbench, and will keep the Silverline Allen keys in order and secure for when they’re needed.
Stanley 097552 1.5 – 8mm Fatmax Locking Hex Key Set Review
A list of hand tools wouldn’t be complete without something from Stanley, and their 097552 FatMax Set is impressive for its size. It’s like a Swiss Army Knife for Allen keys, a hex key set that gives you the best Allen wrench in your pocket for when you need it the most.
It’s the right size to fit into the smallest of tool kits, but still offers a range of Allen key sizes to fit most common bolt heads. The handle is rugged and although a bit bulky, it’s a small price to pay for having all of these hex keys in one place.
Our favourite feature of this best folding Allen key set is the three locking positions available on each hex key. Depending on the situation, you can lock each key out at 90°, 130° or 180°. This is useful for when access is limited, or when you need the handle to give you some extra grip.
Meterk 36 Pc Allen Key Allen Wrench Set Review
Meterk manufacture a range of hand and power tools ranging from the best hex keys to 3D printers. The combination hex key set we tested was the most comprehensive on this list by far, giving you a huge range of both metric Allen and imperial Allen keys to play with.
You might not always come across imperial Allen keys sizes, but with this Meterk 36 Pc large Allen Key set, you’ll never be caught out in an emergency. We really like the included handle; it fits most of the larger hex keys in the set and gives you something solid to hold on to when bolts are tough.
The ball-ends are another innovation usually only found on the best Allen key sets, but are welcome on a set at this end of the budget scale.
Allen Key Set Buyer’s Guide
Hex head bolts are as familiar to DIYers and professional contractors as screws and screwdrivers. They are found on everything from mountain bikes to computers. The best Allen wrench needs to be strong, weather resistant and easy to use.
The best hex keys need to be strong enough to tighten down bolts without bending, but flexible enough so that they can take torsional forces without shattering. The best Allen key socket sets are usually made from steel, with coatings like chrome vanadium for hardness and weather resistance.
The best metric Allen key set is no good if the individual keys are lost at the bottom of a tool box. Luckily sets like the Wera Hex-Plus come with a handy clip to keep them organised, and the Silverline 323710 includes a bench mounted storage rack.
What is an Allen key?
Named after the Allen brand of tools from Hartford, Connecticut in the USA, they are hexagonal shaped lengths of steel that fit snugly into bolt heads, depending on the size. They are also commonly referred to as Allen wrenches or hex keys.
After looking at five of the best Allen key sets, we have to pick a winner. The Wera Hex-Plus is the hands-down favourite after seeing just how many innovations can be made to such a simple tool. The colour coding, clever head shape and carry clip were all excellent features.
