6-40 x 3 Alloy Steel Socket Head Cap Screw is specified when a machine assembly needs a high-strength alloy steel socket screw with predictable head and drive geometry. The exact 6-40 x 3 size helps buyers align the fastener with repair work tied to an existing fastener callout. It is frequently used in manufacturing cells, packaging machinery, and maintenance repair when socket engagement is preferred over external-wrench access. The dimensional highlights make the listing more useful for maintenance shops and industrial distribution teams. The result is a clear alloy steel socket head cap screw listing for purchasing review and procurement. Technical Highlights Material: Alloy Steel Thread: 6-40 Length: 3 in.
