Professional Applications & Engineering Value

This M2 shoulder screw is engineered to solve critical alignment and corrosion challenges in precision assemblies. Manufactured from 316 stainless steel with a passivated finish, it offers outstanding resistance to chemicals and moisture, making it ideal for medical devices, food processing equipment, and marine applications. The precise shoulder fit with tight tolerances on diameter (3 mm) and length (5 mm) ensures components are accurately positioned and remain securely locked, eliminating misalignment and reducing wear. The hex socket head allows for compact, high-torque installation in confined spaces. With a coarse 0.4 mm pitch and Class 6g thread, it provides rapid assembly and reliable performance in vibrating environments, delivering long-term engineering value and operational reliability.

Specification Summary & Compliance

This screw features a Class 6g thread fit per metric standards, ensuring dimensional accuracy and interchangeability. The shoulder is manufactured to precise tolerances: diameter of 3 mm (-0.025 to 0 mm) and length of 5 mm (0 to 0.05 mm). It is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of hazardous substances and suitable for use in regulated industrial and electronic applications.
