Professional Applications & Engineering Value
This 8-32 UNC set screw in 316 Stainless Steel delivers exceptional engineering value for demanding industrial applications where corrosion resistance and reliable positioning are critical. The hex headless design with 5/64" drive allows for secure installation in confined spaces while maintaining high torque capability. The 90° cone point creates concentrated pressure points that prevent component slippage in rotating assemblies, making it ideal for securing collars, gears, and pulleys on shafts. The Class 3A thread fit provides tighter tolerances than standard fasteners, ensuring precise alignment and reduced vibration-induced loosening in machinery, automotive, and aerospace applications. Manufactured to ASME B18.3 specifications, this set screw offers consistent performance in high-temperature and corrosive environments where ordinary fasteners would fail.
Specification Summary & Compliance
This precision fastener features 8-32 UNC coarse threads with Class 3A thread fit for superior dimensional accuracy and engagement. The 3/8" length and 0.164" thread diameter provide optimal sizing for various industrial applications. Manufactured in compliance with ASME B18.3 standards for dimensional consistency and performance reliability. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring environmental responsibility and safety in industrial use.
