5/32 Short Arm Alloy Steel Hex Key is a practical replacement tool when the socket needs full-flat engagement from an in-range hex key. The ASME B18.3 width band is 0.1547-0.1562 in.; the key is held just under nominal so it enters an in-tolerance socket and bears on the flats.
Replacement of rounded or worn keys helps protect expensive socket fasteners during service and teardown. Use the Short Arm series when clearance is limited, and compare the Long Arm twin when added reach is needed.
Cold Headers supports exact-size sourcing for socket-product tooling, including individual alloy steel L-keys. Review the 5/32 in. width, Short Arm format, short-leg length, and arm length before ordering. The Hex Socket Pressure Plugs category is a useful companion when the same maintenance group sources socket-drive plugs. The listed B and C ranges keep the tool geometry tied to this exact catalog row.
