Professional Applications & Engineering Value

This M3 shoulder screw is engineered to address critical alignment and pivot point requirements in precision assemblies. The 316 Stainless Steel construction, enhanced by a passivated finish, provides exceptional resistance to chemicals, moisture, and oxidation, making it ideal for medical devices, food processing equipment, and marine applications. The precise shoulder with minimal tolerances ensures accurate component positioning, reducing wear and misalignment in rotating mechanisms or as a guide for moving parts. The socket head with hex drive allows for compact installation in confined spaces, while the Class 6g thread fit guarantees secure fastening without cross-threading. By integrating high tensile strength and compliance with RoHS 3 and REACH standards, this screw delivers long-term reliability and safety in industrial shoulder screw applications, minimizing downtime and maintenance costs.

Specification Summary & Compliance

This shoulder screw adheres to metric (M3 x 0.5mm) specifications with a Class 6g thread fit for standard coarse threading. The shoulder features precise dimensional control: diameter tolerance of -0.025 to 0 mm and length tolerance of 0 to 0.05 mm. Manufactured from 316 Stainless Steel with a passivated surface treatment, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and material integrity for industrial use.
