Pro-Tip: To maximize the life of your hex keys and the fasteners you are working on, ensure the key is fully seated at the bottom of the socket before applying heavy torque. If you encounter a stubborn or rusted bolt, flip the key to the 90-degree "right-angle" position; this uses the handle length as a lever arm to break the bond without over-straining your wrist.
