0.050 Long Arm Alloy Steel Hex Key covers the 0.050 in. driver position in an alloy steel hex-key range used throughout machine work. The ASME B18.3 width band is 0.0490-0.0500 in.; the key is held just under nominal so it enters an in-tolerance socket and bears on the flats.
Machine setup and changeover work often needs a repeatable L-key at the station rather than a shared tool set. Long Arm geometry adds reach and leverage; the same width in Short Arm form is the natural compact comparison.
Since 1962, Cold Headers has supplied specialty socket hardware and the hex keys that complete the working system. Review the 0.050 in. width, Long Arm format, short-leg length, and arm length before ordering. Cold Headers can review non-catalog widths or arm-series requirements as quote requests. This width is part of the hard-to-find end of the range, where loose-driver restocking is often the real problem.
