3/16 Inch (in) Short Arm Alloy Steel Hex Key is selected when the driver must reach an internal hex socket inside crowded equipment. A properly sized key bears on the socket flats rather than concentrating force at the corners, helping preserve the internal drive.
The single-size listing helps buyers match a known across-flats width without changing the rest of the fastener bill of materials. Cold Headers can quote the listed key or review other sizes when the standard catalog row is not the right match.
Call 773-775-7900 or email Sales@coldheaders.com for pricing, availability, production quantities, or other quoted sizes.
