Professional Applications & Engineering Value
This black-oxide alloy steel set screw with Class 3A UNF threads and cone point design solves critical engineering challenges in precision machinery, automotive components, and industrial equipment. The fine thread spacing provides superior resistance to vibrational loosening, while the 118° cone point angle ensures maximum bite and positioning accuracy in shaft collars, gears, and pulleys. The headless configuration with 3/16" hex drive enables flush mounting in confined spaces where protruding fasteners are impractical. Manufactured to ASME B18.3 specifications, these set screws deliver reliable performance in high-stress applications requiring precise component alignment and secure fastening.
Specification Summary & Compliance
This precision fastener features 3/8"-24 UNF Class 3A threads with fine thread spacing, manufactured from alloy steel with Rockwell C45 hardness. The 5/16" length and cone point with 118° angle provide optimal engagement depth. Compliant with ASME B18.3 standards (ASTM F912), RoHS 3 (2015/863/EU), and REACH (EC 1907/2006) regulations, ensuring environmental compliance and material safety for industrial applications worldwide.
