7/8-9 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. For tooling plates, the 7/8-9 thread and 3 in. length help confirm the correct socket cap screw before installation. Industrial buyers may specify it for maintenance shops, tooling, and material handling where head geometry and drive access need to be predictable. The dimensional highlights make the listing more useful for maintenance shops and industrial distribution teams. This keeps the listing focused on the fastener geometry rather than broad catalog language. Technical Highlights Material: Alloy Steel Thread: 7/8-9 Length: 3 in. Nominal Body Diameter: .875 in.
