Professional Applications & Engineering Value

This M2 shoulder screw is engineered to address critical alignment and pivot point challenges in precision assemblies. Manufactured from 316 stainless steel, it provides excellent resistance to chemicals and corrosion, making it suitable for medical devices, food processing equipment, and marine applications. The 45mm shoulder length acts as a precise spacer or axle, reducing wear on moving parts and maintaining accurate positioning. The black oxide finish on the socket head shoulder screw not only enhances its aesthetic but also adds a protective layer against seizing. With a Rockwell B79 hardness and high tensile strength, it ensures long-term reliability in dynamic or vibrating environments, solving common failures associated with inferior fasteners.

Specification Summary & Compliance

This metric shoulder screw features a Class 5g6g thread fit per ISO standards, ensuring precise thread engagement. The shoulder diameter tolerance is -0.072 to -0.01 mm, and the shoulder length tolerance is 0 to 0.25 mm, guaranteeing high dimensional accuracy. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial applications.
