Allen wrenches are undeniably useful, but they can also cause headaches. They’re slender, which doesn’t leave a lot of room for easy-to-read size markings, and they’re easy to drop, particularly when you have to awkwardly fit them into tight spaces. The good news is that there are hex key sets on the market that solve these problems, including one that’s nearly half off at Amazon right now.

The Disen 18-Piece Color-Coded Hex Key Set is on sale for $14 at Amazon, 47% off of its typical $27 price tag. This deal is good on the 18-piece color-coded model, but there are other discounts available on bigger and smaller sets with hex or torx heads. This option comes with both metric and SAE wrenches, so it should be the only set of hex keys you ever need.

Each of the 18 hex keys in this set is made of chrome vanadium steel, a material prized by toolmakers for its waterproofness, high strength, and toughness in extreme cold and hot temperatures. They’re longer than the competition — the longest is 8.87 inches versus 3.15 inches on some other models — which means they’re easier to handle and harder to drop. And most noticeably, they’re color-coded, so it’s easy to find the piece you need and store them in the correct order in the folding organizer, as long as you remember ROYGBIV. The short end of the wrenches has a traditional end, while the longer one has a ball end that’s easier to use at awkward angles.

One shopper wrote that “everyone should have a set like this on hand” because size labeling “plus the color coding makes it easy to quickly pick out” the wrench you need. On top of that, the “actual quality of the Allen wrenches is top-notch, and their extended length makes it a lot easier to grip them and turn with some actual leverage” than shorter options.

Another shopper wrote that these hex keys “look nice, they work nice, and the extra length makes them extra versatile.” On top of that, the “ball-end allows for easy starting in tighter spots” and the “storage holders work well to keep them contained.”
