- Enhanced component protection with soft nylon tip preventing surface damage to mating parts during clamping
- Reliable positioning accuracy with headless design allowing flush mounting in precision assemblies
Professional Applications & Engineering Value
This 6-32 UNC set screw with nylon tip delivers critical vibration resistance in demanding industrial applications where traditional fasteners fail. The 18-8 stainless steel construction provides excellent corrosion resistance for machinery exposed to moisture, chemicals, or outdoor elements. Engineered with Class 3A thread fit and coarse threading, it ensures rapid assembly while maintaining precise clamping force in right-hand thread configurations. The headless hex drive design enables installation in tight spaces where conventional screw heads cannot fit, making it ideal for precision equipment, motor shafts, and adjustable mechanisms requiring secure, non-marring fastening solutions that withstand thermal cycling and mechanical stress.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit and UNC coarse threading. This 1/8" long set screw features a 1/16" hex drive and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards. The 18-8 stainless steel material maintains Rockwell B80 hardness while the nylon tip operates within specified temperature ranges of -50° to 250°F.
