Professional Applications & Engineering Value
This precision 3/8"-16 UNC shoulder screw delivers exceptional engineering value in applications requiring exact component alignment and rotational control. The 18-8 stainless steel construction with passivated finish provides superior corrosion resistance for machinery operating in demanding industrial environments. The precisely machined 1/2" diameter shoulder ensures accurate positioning of moving parts in assemblies, eliminating misalignment issues that can lead to premature wear. The low profile socket head design allows for compact installations while maintaining accessibility for maintenance. These shoulder screws are particularly valuable in precision equipment, automation systems, and rotating assemblies where dimensional stability and corrosion resistance are critical for long-term reliability and reduced maintenance cycles.
Specification Summary & Compliance
This shoulder screw features Class 2A thread fit tolerance for consistent engagement, UNC coarse thread spacing for rapid assembly, and precise shoulder diameter tolerance of -0.001" to 0" for exact alignment. Manufactured to industry standards with RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance, ensuring environmental responsibility and global regulatory acceptance for industrial applications.
