1/16 Short Arm Alloy Steel Hex Key is selected when a worn or undersize key should be replaced before it damages the screw socket. The ASME B18.3 width band is 0.0615-0.0625 in.; the key is held just under nominal so it enters an in-tolerance socket and bears on the flats.
Repair benches use short and long formats to cover both open access and recessed socket locations. Many buyers stock the Short Arm key beside its Long Arm twin so the same width is available in both geometries.
Cold Headers keeps this driver family tied to the broader socket-fastener catalog rather than treating it as a commodity tool. Review the 1/16 in. width, Short Arm format, short-leg length, and arm length before ordering. Hex Socket Pressure Plugs are a related catalog section for buyers sourcing socket-drive closure hardware.
