3/8-16 x 6 1/2 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. For repair inventories, the 3/8-16 thread and 6 1/2 in. length help confirm the correct socket cap screw before installation. Selected for manufacturing cells, manufacturing plants, and fixture design, it gives maintenance teams a searchable alloy steel socket screw callout. The socket head form provides a cylindrical head suited to counterbores and recessed mounting pockets. This keeps the listing focused on the fastener geometry rather than broad catalog language.
