Professional Applications & Engineering Value

This 8-32 UNC shoulder screw delivers critical engineering solutions where precision alignment and high strength are paramount. Manufactured from 17-4 PH Stainless Steel, it provides outstanding corrosion resistance for machinery, automotive, and aerospace assemblies exposed to demanding conditions. The 1" shoulder length acts as a precise spacer or pivot in rotating mechanisms, reducing wear on connected components. With its hex socket drive and knurled head texture, installation is secure and efficient, even in confined spaces. The Class 3A thread fit and coarse UNC threading ensure rapid assembly with minimal cross-threading risk, making it ideal for high-volume production environments requiring consistent performance and reduced maintenance downtime.

Specification Summary & Compliance

This shoulder screw features precision dimensions including a 3/16" shoulder diameter with -0.004" to -0.002" tolerance and 1" shoulder length with ±0.005" tolerance. Thread specifications include 8-32 UNC coarse thread with Class 3A fit for superior engagement. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material transparency for global industrial applications.
