Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers critical engineering solutions where vibration resistance and permanent positioning are paramount. The Class 3A thread fit provides superior tolerance control that prevents loosening in high-stress applications including machinery components, power transmission systems, and precision equipment. The hex drive configuration allows for high-torque installation in confined spaces where headless fasteners are required. UNC coarse threads facilitate rapid assembly while the flat tip design ensures maximum surface contact for secure shaft collars, gears, and pulley retention. Engineered to withstand industrial environments, the combination of Rockwell C45 hardness and protective black-oxide finish provides durable performance in manufacturing, automotive, and heavy equipment applications.

Specification Summary & Compliance

This 3/8"-16 UNC set screw features precision Class 3A thread fit with coarse thread spacing for optimal engagement. Manufactured to ASME B18.3 specifications with Rockwell C45 hardness rating, the fastener maintains dimensional accuracy throughout its service life. The product is fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations, ensuring environmental responsibility in industrial supply chains. The 7/16" length and 0.375" thread diameter provide standardized dimensions for consistent performance across applications.
