Professional Applications & Engineering Value

This precision shoulder screw is engineered to address common challenges in machinery assembly, such as misalignment and component wear. Made from 18-8 stainless steel with a passivated finish, it resists rust and chemical exposure, making it suitable for automotive, electronics, and food processing equipment. The low profile socket head and hex drive allow for compact designs and easy access in tight spaces, while the precisely machined shoulder (6mm diameter, 5mm length) acts as a reliable pivot or spacer, reducing stress on threaded sections. Its Class 6g thread fit and coarse thread pitch ensure quick installation and high holding power, minimizing downtime in production lines.

Specification Summary & Compliance

This M5 shoulder screw features a metric coarse thread (M5x0.8) with Class 6g thread fit for standard tolerance. Shoulder dimensions include a diameter of 6 mm (tolerance: -0.025 to 0 mm) and length of 5 mm (tolerance: 0 to 0.05 mm), ensuring precise assembly. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting use in environmentally conscious applications.
