2-64 x 1 Alloy Steel Socket Head Cap Screw helps maintenance and engineering teams source an alloy steel internal-hex screw with verified head-size data. The size callout supports repair work tied to an existing fastener callout when socket-drive service locations cannot accept a substitute fastener. It is frequently used in automation systems, fixture design, and tooling when socket engagement is preferred over external-wrench access. The dimensional highlights make the listing more useful for maintenance shops and industrial distribution teams. Those verified dimensions support counterbore checks, tool selection, and replacement fastener review. Technical Highlights Material: Alloy Steel Thread: 2-64 Length: 1 in.
