  • Reliable thread performance with Class 3A fit and UNC coarse threads, providing vibration resistance
  • Consistent mechanical strength backed by Rockwell B80 hardness for long-term durability
  • Space-saving headless design allowing flush mounting in tight assembly applications
  • Environmental compliance assurance meeting RoHS 3 and REACH standards for safe usage

Professional Applications & Engineering Value

This 6-32 UNC set screw delivers exceptional engineering value in precision assembly applications where vibration resistance and corrosion protection are critical. The 18-8 stainless steel material prevents rust formation in manufacturing environments, while the Class 3A thread fit ensures tight tolerances for secure fastening in machinery components, electrical enclosures, and precision instruments. The extended tip design creates deeper penetration into mating parts, solving common loosening issues in high-vibration industrial equipment. With coarse UNC threads and right-hand threading, installation becomes more efficient in production lines, reducing assembly time while maintaining superior holding power in demanding applications.

Specification Summary & Compliance

This set screw maintains precision inch dimensions with thread diameter of 0.138" and length of 3/16". The Class 3A thread fit ensures tight tolerance performance, manufactured in compliance with ASME B18.3 specifications. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, confirming safe usage in various industrial sectors. The extended tip maintains dimensional accuracy with diameter tolerance of -0.005" to 0" and length tolerance of -0.005" to 0".
