Professional Applications & Engineering Value

This 8-32 UNC thread set screw delivers exceptional engineering value in precision assembly applications where vibration resistance and reliable positioning are critical. The black-oxide alloy steel construction provides superior corrosion resistance compared to standard finishes, while the Rockwell C28 hardness ensures dimensional stability under load. The soft green nylon 6/6 tip creates a secure, non-marring contact surface that maintains grip in high-vibration environments like machinery, automotive components, and electrical enclosures. The coarse thread spacing and Class 3A thread fit enable rapid installation with consistent clamping force, making these headless hex drive screws ideal for precision alignment applications where space is limited and reliability is paramount.

Specification Summary & Compliance

This set screw features precision 8-32 UNC threads with Class 3A fit for tight tolerance applications, manufactured to ASME B18.3 dimensional standards. The product maintains full compliance with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety. The right-hand thread direction with coarse thread spacing ensures compatibility with standard industrial components, while the 3/16" length and 5/64" hex drive provide consistent installation characteristics across production runs.
