Professional Applications & Engineering Value
This Black-Oxide Alloy Steel set screw delivers critical performance advantages in precision assembly applications where vibration resistance and corrosion protection are paramount. The 10-32 UNF Class 3A fine threads provide superior engagement in tapped holes, minimizing loosening under dynamic loads common in machinery, automotive components, and power transmission systems. The cup point tip creates a permanent indentation in mating surfaces, ensuring secure positioning of gears, pulleys, and collars on shafts. With Rockwell C45 hardness, this headless set screw maintains its structural integrity under high clamp loads while the black-oxide surface treatment provides essential protection against oxidation in demanding industrial environments.
Specification Summary & Compliance
This set screw features precision 10-32 UNF Class 3A threads with fine thread spacing and right-hand orientation. Manufactured to ASME B18.3 specifications with material certification to ASTM F912. The component meets RoHS 3 (2015/863/EU) compliance for restricted substances and REACH (EC 1907/2006) regulations regarding chemical safety. Dimensions include 7/8" length, 0.19" thread diameter, and 3/32" hex drive size, ensuring interchangeability and reliable performance in industrial fastening applications.
