Professional Applications & Engineering Value
This 6-32 UNC shoulder screw delivers critical engineering value through its precision shoulder design and 18-8 stainless steel construction. The passivated finish provides superior corrosion protection in demanding environments like manufacturing equipment, automation systems, and precision instruments. The hex socket head enables secure fastening in tight spaces while the coarse UNC threads ensure rapid assembly without compromising strength. The precisely controlled shoulder diameter and length eliminate component misalignment, reducing wear and maintaining operational accuracy in rotating assemblies and pivot points. This combination of features solves common industrial challenges including vibration-induced loosening, corrosion failure, and assembly inaccessibility.
Specification Summary & Compliance
This precision 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". Manufactured from 18-8 stainless steel with passivated finish, it delivers consistent performance with 70,000 psi tensile strength and Rockwell B55 hardness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance for industrial applications.
