Professional Applications & Engineering Value

This 8-32 UNC shoulder screw is engineered to address critical challenges in precision assemblies where vibration loosening and misalignment can compromise performance. The 18-8 stainless steel construction provides inherent corrosion resistance, while the nylon patch thread locker offers permanent anti-vibration properties without requiring additional adhesives. The precise shoulder diameter tolerance (-0.001" to 0") ensures accurate component positioning in machinery, automotive, and electronic enclosures, preventing lateral movement that could lead to premature wear. With its coarse UNC threads and Class 2A fit, installation is streamlined while maintaining secure fastening in high-stress industrial environments where reliability is paramount.

Specification Summary & Compliance

This shoulder screw features Class 2A thread fit with UNC coarse threading standards, precise shoulder diameter tolerance of -0.001" to 0", and shoulder length tolerance of 0" to 0.002". The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for industrial applications worldwide.
