Professional Applications & Engineering Value
This 8-32 UNC set screw delivers critical engineering solutions for industrial applications where vibration resistance and corrosion protection are paramount. The Black-Oxide Alloy Steel construction with Rockwell C45 hardness prevents rust in humid or chemically aggressive environments, while the Class 3A thread fit maintains precise tolerances in machinery, automotive, and precision equipment assemblies. The headless design with cup tip creates permanent, flush fastening points for shafts, collars, and gears, eliminating loosening from continuous operation. Engineered with coarse UNC threads and 5/64" hex drive, it enables rapid installation in high-volume manufacturing while meeting rigorous ASME B18.3 specifications for dimensional consistency.
Specification Summary & Compliance
This set screw maintains Class 3A thread fit per UNC standards with 8-32 thread size and 0.164" diameter, ensuring precision alignment. Manufacturing complies with ASME B18.3 dimensional specifications and material standards per ASTM F912. Regulatory compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) for environmental safety. The 3/4" length and cup tip design provide consistent engagement depth for reliable fastening in industrial assemblies.
