7/64 Short Arm Alloy Steel Hex Key is a row-specific alloy steel hex key for buyers matching tool crib stock to socket-product drawings. The ASME B18.3 width band is 0.1079-0.1094 in.; the key is held just under nominal so it enters an in-tolerance socket and bears on the flats.
Production cells often keep common widths at the fixture so operators do not borrow the wrong driver. The Short Arm key is the compact member of the pair, while the Long Arm version covers deeper socket access.
For industrial purchasing and maintenance teams, Cold Headers helps match width, series, and catalog identity. Review the 7/64 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. That context helps purchasing compare the driver geometry without adding unsupported performance claims.
