Professional Applications & Engineering Value
This precision shoulder screw delivers critical engineering solutions where component alignment and vibration resistance are paramount. The 18-8 stainless steel construction provides excellent corrosion resistance for demanding environments including manufacturing equipment, automotive assemblies, and electronic enclosures. The nylon patch locking technology eliminates the need for separate locking washers or adhesives, simplifying assembly while providing reliable vibration resistance across wide temperature ranges. The precisely controlled shoulder diameter and length with tight tolerances ensures accurate positioning of moving parts in pivots, linkages, and bearing applications. The combination of UNC coarse threading with Class 2A fit guarantees consistent engagement in high-volume production settings, reducing assembly time and improving manufacturing efficiency.
Specification Summary & Compliance
This shoulder screw features 8-32 UNC coarse threads with Class 2A thread fit for consistent engagement. The shoulder maintains precise dimensional control with diameter tolerance of -0.001" to 0" and length tolerance of 0" to 0.002". Manufactured from 18-8 stainless steel with Rockwell B55 hardness and 70,000 psi tensile strength. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for use in regulated industries and international markets.
