Professional Applications & Engineering Value

This M5 shoulder screw is engineered to solve critical alignment and durability challenges in industrial applications. The 18-8 stainless steel material offers excellent resistance to corrosion and oxidation, making it suitable for machinery, automation systems, and outdoor equipment. The 20mm shoulder length acts as a precise pivot or spacer, ensuring accurate positioning of moving parts like gears, pulleys, and linkages, which minimizes wear and extends service life. The socket head with hex drive allows for compact designs and high clamping force in confined spaces. With its coarse thread pitch and Class 5g6g thread fit, it resists loosening under vibration, providing long-term reliability in dynamic assemblies. This screw is a trusted component for engineers seeking precision shoulder bolts that enhance performance and reduce maintenance.
