Professional Applications & Engineering Value
This 6-32 UNC hex headless set screw delivers critical engineering solutions where space constraints and component protection are paramount. The 18-8 stainless steel construction provides excellent corrosion resistance in harsh environments, while the Rockwell B80 hardness ensures durability under repeated adjustments. The green nylon 6/6 tip offers superior marring prevention for sensitive surfaces, maintaining performance across a wide temperature range from -50° to 250°F. Particularly valuable in precision assemblies, the Class 3A thread fit guarantees consistent clamping force without damaging shaft surfaces, making it ideal for positioning components in machinery, automotive systems, and electronic enclosures where vibration resistance and reliable positioning are critical.
Specification Summary & Compliance
This set screw features 6-32 UNC coarse threads with Class 3A thread fit for precision engagement, manufactured to ASME B18.3 standards. The 1/16" hex drive provides secure torque application, while the 3/16" length and headless design optimize space utilization. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications requiring strict material restrictions.
