Professional Applications & Engineering Value
This 10-24 UNC set screw delivers exceptional performance in demanding industrial applications where vibration resistance and precise component positioning are critical. The black-oxide alloy steel construction provides superior corrosion resistance while maintaining the Rockwell C45 hardness needed for high-stress environments. The nylon patch locking technology effectively prevents loosening under continuous vibration, making it ideal for machinery, automotive assemblies, and precision equipment. The coarse UNC thread with Class 3A fit ensures quick installation and reliable engagement, while the cup tip design maximizes gripping force on shafts, collars, and pulleys. This headless set screw solves common engineering challenges of space constraints and vibration-induced failures in industrial fastening systems.
Specification Summary & Compliance
This precision set screw features 10-24 UNC coarse threads with Class 3A thread fit for superior dimensional accuracy. Manufactured to ASME B18.3 specifications and meeting ASTM F912 standards, it ensures consistent performance across industrial applications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, providing assurance for use in regulated industries and international markets.
