Professional Applications & Engineering Value

This 18-8 stainless steel shoulder screw delivers exceptional engineering value in precision assembly applications where alignment accuracy and corrosion resistance are critical. The 2-56 UNC coarse thread configuration provides superior holding power in softer materials while resisting vibration-induced loosening. The precisely machined shoulder diameter and extended 1 1/4" shoulder length ensure perfect component spacing in machinery, automation systems, and electronic enclosures. The combination of 70,000 psi tensile strength and Rockwell B55 hardness makes this socket head shoulder screw ideal for high-stress applications where fastener failure is not an option. The knurled head texture and 5/64" hex drive provide secure tool engagement during installation, preventing slippage in confined spaces common in industrial equipment maintenance and precision manufacturing environments.
