Professional Applications & Engineering Value

This precision 8-32 UNC shoulder screw delivers critical engineering solutions where component alignment and vibration resistance are paramount. The 18-8 stainless steel construction provides excellent corrosion resistance for machinery exposed to moisture, chemicals, or outdoor elements. The nylon patch locking technology effectively prevents thread loosening in high-vibration applications such as motor mounts, conveyor systems, and automated equipment. With its 3/16" shoulder length maintaining precise diameter tolerance, this fastener ensures accurate pivot points and bearing surfaces in assemblies requiring rotational or linear movement. The combination of Class 2A thread fit and controlled shoulder specifications makes it ideal for precision instruments, manufacturing jigs, and robotic assemblies where dimensional accuracy directly impacts performance and longevity.

Specification Summary & Compliance

This shoulder screw features 8-32 UNC coarse threading with Class 2A thread fit for standard industrial applications. The shoulder maintains precise dimensional control with diameter tolerance of -0.001" to 0" and length tolerance of 0" to 0.002". Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance for global distribution and use in regulated industries.
