Professional Applications & Engineering Value

This low profile socket head shoulder screw with 8-32 UNC thread and 3/16" shoulder diameter solves critical alignment challenges in precision assemblies. The 18-8 stainless steel construction combined with passivated finish provides superior corrosion resistance for demanding environments like manufacturing equipment, automation systems, and electronic enclosures. The precise shoulder fit eliminates component wobble while serving as an axle or pivot point in mechanisms requiring rotational movement. Engineers specify this shoulder screw for applications where exact component positioning is crucial, such as in precision machinery, robotic arms, and optical equipment assemblies. The hex drive and low profile head design allow for efficient installation in space-constrained applications while maintaining high tensile strength for durable performance.

Specification Summary & Compliance

This shoulder screw maintains Class 2A thread fit with UNC coarse thread spacing and right-hand thread direction for standard compatibility. The shoulder features tight diameter tolerance (-0.001" to 0") and length tolerance (0" to 0.002") for precision applications. Manufactured to industry standards with RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory acceptance for industrial use worldwide.
