Professional Applications & Engineering Value

This 316 stainless steel socket head cap screw is engineered to address critical challenges in corrosive environments such as chemical processing, marine equipment, and outdoor machinery. The combination of 10-32 UNF fine threads and Class 3A fit ensures minimal backlash and superior resistance to loosening under dynamic loads. The passivated finish enhances surface durability, reducing the risk of galling and extending service life in high-moisture or acidic conditions. With a 70,000 psi tensile strength, it provides reliable performance in structural assemblies, precision instruments, and heavy-duty fixtures where failure is not an option. The hex drive socket head allows for efficient installation in tight spaces, streamlining maintenance and reducing downtime in industrial operations.

Specification Summary & Compliance

This socket head cap screw adheres to inch system measurements with a Class 3A thread fit for precise dimensional accuracy. It features a 10-32 UNF fine thread with right-hand direction and is fully threaded along its 1 1/2" length. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability. The Rockwell B70 hardness and specified tensile strength confirm consistent performance under standardized mechanical testing protocols.
