Allen key is what?

Explanation:
An Allen key is an L-shaped hex key used to drive screws that have a hexagonal socket in the head. The six flat surfaces of the key fit snugly into the socket, so turning the key transfers torque directly to the screw and helps prevent slipping or stripping. The L shape gives leverage: the longer arm acts as a handle and the shorter arm reaches into tight spaces. This tool is specifically for hex recess screws, unlike a curved tool for bending, a pin, or a nut and bolt. You’ll commonly find it in furniture, bicycles, and various assemblies, with sizes in metric or imperial units, and some sets include ball-end versions for angled access.
