ASTM A307 Grade A Socket Head Cap Screws

ASTM A307 Socket Head Cap Screws (SHCS) are specialized fasteners made from low-carbon steel and characterized by a cylindrical head with a hexagonal recess (socket) for driving with an Allen wrench. Although SHCS are typically made from high-strength alloy steel, manufacturing them to the A307 Grade A specification provides a cost-effective option for applications requiring a streamlined, recessed head design but only demanding moderate strength (60 ksi minimum tensile strength). These Socket Head Cap Screws are commonly used in machine tool assemblies, tight-clearance equipment, and general fabrication where the smooth, flush profile of the socket head is beneficial. Zeron Fasteners manufactures and supplies A307 SHCS, offering both fully and partially threaded options to meet various general assembly and machine maintenance needs.
