7/32 Short Arm Alloy Steel Hex Key gives tool cribs a short arm driver for socket fasteners that need a correctly sized hex key. The ASME B18.3 width band is 0.2172-0.2187 in.; the key is held just under nominal so it enters an in-tolerance socket and bears on the flats.

Die and mold work can require dedicated driver sizes near tooling plates, clamps, and adjustment hardware. 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 7/32 in. width, Short Arm format, short-leg length, and arm length before ordering. The listed B and C ranges keep the tool geometry tied to this exact catalog row.
