Professional Applications & Engineering Value

This precision shoulder screw delivers exceptional value in applications requiring exact component positioning and rotational stability. The 18-8 Stainless Steel material combined with passivated finish provides excellent resistance to oxidation and chemical exposure, making it suitable for machinery, automation systems, and electronic enclosures operating in corrosive environments. The precisely machined 1 1/8" shoulder with minimal diameter tolerance serves as a reliable bearing surface or pivot point, eliminating the need for additional bushings in assemblies. With its hex socket head and 8-32 UNC coarse threads, installation is streamlined while maintaining Class 2A thread fit accuracy for consistent clamping force. These features collectively reduce assembly time, minimize component wear, and enhance equipment longevity in precision manufacturing and industrial automation applications.

Specification Summary & Compliance

This shoulder screw maintains Class 2A thread fit per UNC standards with precise shoulder diameter tolerance of -0.001" to 0" and shoulder length tolerance of 0" to 0.002". Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability. The inch-system measurement and UNC thread specifications guarantee compatibility with standard industrial equipment and replacement part requirements.
