These are the only hex key sets you should consider.

Also great
“These are more expensive than our main pick and the case doesn’t fold open, so it can get a little awkward. Still, they are better than the other sets we tested.”

Our pick
“These hex keys (also known as Allen wrenches) are ideal for tight spots, and their easy-to-use case makes it simple to remove and replace even the tiniest wrenches. Backed by a lifetime guarantee.”
