Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical challenges in precision assemblies, such as misalignment and component wear. The 40mm shoulder length with minimal tolerance provides a stable pivot or spacer, reducing stress on threaded sections and enhancing machine longevity. Constructed from 18-8 stainless steel with a passivated finish, it resists corrosion in moist or chemical-laden settings, making it ideal for industrial machinery, automation systems, and mechanical linkages. The low-profile socket head and hex drive allow for compact designs and easy tool access, streamlining maintenance in tight spaces while the Class 6g thread fit ensures reliable engagement in high-vibration environments.

Specification Summary & Compliance

This precision shoulder screw adheres to Metric standards with an M5x0.8 coarse thread and Class 6g thread fit for consistent performance. Shoulder dimensions include a diameter of 6 mm (tolerance: -0.025 to 0 mm) and length of 40 mm (tolerance: 0 to 0.05 mm), ensuring exacting precise fit. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and suitability for global industrial applications.
