About Klein Tools 70590 Compact Folding Hex Key
This versatile tool combines six commonly used SAE (inch) sizes and six common metric (mm) sizes into one convenient, pocketable design. The hex keys are made of heat-treated chromium-vanadium (CR-V) alloy steel with a black phosphate finish for strength and rust prevention, housed in a durable, orange-colored reinforced nylon handle. Reviewers praise its sturdy build and the convenience of having both measurement standards in one place, which helps prevent lost individual keys.
