Professional Applications & Engineering Value
This 316 stainless steel square head set screw is engineered to solve critical challenges in demanding applications such as machinery, marine equipment, and chemical processing systems. Its high corrosion resistance prevents failure in moist or corrosive environments, while the coarse UNC thread and Class 2A fit ensure rapid, vibration-resistant fastening. The square head design with an external drive allows for high-torque application without cam-out, making it ideal for permanent or semi-permanent set screw uses where disassembly is infrequent. By combining robust material properties with precise ASME B18.6.2 standards, this fastener delivers long-term reliability, reducing maintenance needs and downtime in industrial set screw applications.
Specification Summary & Compliance
This set screw adheres to Class 2A thread fit tolerances for consistent performance and features a 3/8"-16 UNC coarse thread with right-hand direction. Manufacturing and dimensional criteria strictly follow the ASME B18.6.2 standard. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are met for global industrial supply.
