7/32 Long 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 0.2172-0.2187 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. Use the Long Arm series for deeper access, and compare the Short Arm twin when space around the socket is tight.
Cold Headers supports exact-size sourcing for socket-product tooling, including individual alloy steel L-keys. Review the 7/32 in. width, Long 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.
