5/16-18 x 7 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 stockroom identification and purchasing review when fixture clamps cannot accept a substitute fastener. Industrial buyers may specify it for industrial facilities, manufacturing plants, and automation systems 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. The result is a clear alloy steel socket head cap screw listing for purchasing review and procurement. Technical Highlights Material: Alloy Steel Thread: 5/16-18 Length: 7 in.
