1-8 x 2 1/4 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 drawn-to-print replacement work, the 1-8 thread and 2 1/4 in. length help confirm the correct socket cap screw before installation. It is frequently used in packaging machinery, maintenance repair, and maintenance shops 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: 1-8 Length: 2 1/4 in.
