1-72 x 3/8 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 exact 1-72 x 3/8 size helps buyers align the fastener with repair work tied to an existing fastener callout. It is frequently used in engineering departments, machine tools, and industrial facilities when socket engagement is preferred over external-wrench access. Socket engagement helps technicians apply installation torque from above the head in constrained layouts. The combination of product name, size, material, and verified head data improves search clarity for engineers and buyers. Technical Highlights Material: Alloy Steel Thread: 1-72 Length: 3/8 in.
