Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers exceptional engineering value through its specialized material composition and structural design. The alloy steel construction with Rockwell C45 hardness provides the necessary strength to withstand high stress applications while resisting deformation. The 90° cone point creates permanent seating in shafts, collars, and pulleys, solving critical vibration-induced loosening problems in rotating equipment. With UNC coarse threads and Class 3A thread fit, installation is streamlined while maintaining precise tolerances for secure fastening in industrial machinery, automotive components, and power transmission systems. The headless design with hex drive offers space efficiency without compromising torque capability, making it ideal for applications where protruding fastener heads are impractical.

Specification Summary & Compliance

This set screw features precise 3/8"-16 UNC coarse threads with Class 3A thread fit for superior dimensional accuracy and engagement. Manufacturing complies with ASME B18.3 specifications and ASTM F912 material standards. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and chemical safety in industrial applications worldwide.
