7/8-9 x 5/8 Alloy Steel Socket Head Cap Screw is a socket head cap screw for buyers matching an exact thread and length to drawings, repair records, or stocked hardware. The size callout supports matching drawings and maintenance records when machine frames and brackets cannot accept a substitute fastener. Industrial buyers may specify it for manufacturing cells, precision assemblies, and processing equipment where head geometry and drive access need to be predictable. Internal hex drive access helps installation in compact assemblies, guards, housings, and fixture plates. The result is a clear alloy steel socket head cap screw listing for purchasing review and procurement. Technical Highlights Material: Alloy Steel Thread: 7/8-9 Length: 5/8 in.
