Professional Applications & Engineering Value
This precision shoulder screw is engineered to address critical alignment and durability challenges in machinery, automation, and aerospace assemblies. The 1/2" shoulder diameter with minimal tolerance provides a stable pivot or bearing surface, minimizing wear and misalignment in rotating parts. Made from 18-8 stainless steel with a passivated finish, it resists oxidation and chemical exposure, extending service life in corrosive settings. The hex socket head and coarse UNC thread streamline installation in tight spaces, reducing downtime. Ideal for jigs, fixtures, and linkages, this screw ensures reliable performance under high-stress conditions, supported by its 70,000 psi tensile strength and Rockwell B55 hardness.
Specification Summary & Compliance
This shoulder screw features a 3/8"-16 UNC thread with Class 2A fit for precise thread engagement, and a shoulder diameter tolerance of -0.001" to 0" with length tolerance of 0" to 0.002" for accurate assembly. It meets MS51576-37 (NASM51576) specifications, ensuring consistent manufacturing quality. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to environmental and safety regulations for global industrial use.
