Professional Applications & Engineering Value

This 3/8"-16 UNC square head set screw delivers critical engineering solutions for industrial applications where vibration resistance and secure positioning are paramount. The black-oxide alloy steel construction provides superior corrosion protection while maintaining the Rockwell C45 hardness needed for high-strength requirements. The extended tip design ensures deeper penetration into mating components, preventing loosening under dynamic loads. Ideal for machinery assembly, automotive components, and heavy equipment where Class 2A thread fit guarantees consistent engagement and the square head allows for high-torque installation without stripping. These set screws address common industrial challenges of component slippage and fastener failure in high-stress environments.

Specification Summary & Compliance

This set screw features 3/8"-16 UNC coarse threads with Class 2A thread fit for standard industrial applications. Manufacturing complies with ASTM F912 specifications for dimensional accuracy and performance. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring environmental safety standards. Tip dimensions maintain tight tolerances with tip length tolerance of -0.005" to 0.005" and tip diameter tolerance of -0.009" to 0" for precision assembly.
