Professional Applications & Engineering Value
This 3/8"-16 UNC Class 3A stainless steel set screw is engineered to solve critical fastening challenges in machinery, automotive, and assembly lines. The 18-8 stainless steel material offers excellent resistance to rust and oxidation, ensuring long-term reliability in humid or corrosive conditions. Its extended tip design and coarse thread spacing enhance grip on shafts, pulleys, and collars, preventing loosening from vibrations—a common industrial pain point. The hex drive and headless configuration allow for compact installations in tight spaces, while the Rockwell B80 hardness maintains structural integrity under repetitive stress. Ideal for securing components in high-torque environments, this set screw delivers consistent performance, reducing maintenance needs and downtime.
Specification Summary & Compliance
This set screw adheres to ASME B18.3 specifications, ensuring dimensional accuracy and interchangeability. Threads are manufactured to UNC coarse thread standards with a Class 3A fit for precise, tight tolerances. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and safe for various industrial applications.
