Professional Applications & Engineering Value

This 18-8 stainless steel shoulder screw delivers critical engineering solutions where precision alignment and corrosion resistance are paramount. The passivated finish enhances surface durability while the precisely controlled shoulder diameter (7/32") and length (1/8") with tight tolerances ensure accurate component positioning in machinery, automation systems, and precision instruments. The hex socket drive design allows for high-torque installation in confined spaces, while the 8-32 UNC coarse threads provide reliable fastening in vibration-prone applications. With 70,000 psi tensile strength, this fastener maintains structural integrity under significant mechanical stress, making it ideal for industrial equipment, manufacturing jigs, and precision assemblies requiring repeated maintenance cycles.

Specification Summary & Compliance

Manufactured to exacting standards, this shoulder screw features Class 2A thread fit per UNC specifications with precise shoulder diameter tolerance (-0.001" to 0") and shoulder length tolerance (0" to 0.002"). The fastener complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility. The inch-system measurements and right-hand thread direction follow industry-standard practices for compatibility with existing equipment and tooling.
