Professional Applications & Engineering Value
These 8-36 UNF set screws deliver critical engineering solutions for precision assembly applications where vibration resistance and permanent component positioning are paramount. The 18-8 stainless steel composition provides excellent corrosion resistance for demanding environments including marine, chemical processing, and outdoor equipment. The headless hex drive design allows for flush mounting in space-constrained applications while maintaining high torque capability. The cup point tip creates superior biting action into shafts and rotating components, preventing slippage in high-torque applications. With Class 3A thread fit and UNF fine threading, these set screws maintain secure fastening in vibrating machinery, precision instruments, and automotive assemblies where loosening could cause catastrophic failure.
Specification Summary & Compliance
This 8-36 UNF set screw features precise Class 3A thread fit tolerance with 0.164" thread diameter and 1/2" length. Manufactured to ASME B18.3 specifications with 5/64" hex drive and right-hand thread direction. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets.
