Professional Applications & Engineering Value

This M12 shoulder screw delivers critical engineering value in precision assemblies where alignment and spacing are paramount. The 316 stainless steel material provides exceptional resistance to chemicals, saltwater, and industrial contaminants, making it ideal for marine equipment, food processing machinery, and chemical processing systems. The 35mm shoulder length with precise diameter control acts as a permanent spacer or pivot point, eliminating the need for additional bushings and reducing assembly complexity. Combined with the black oxide finish, it offers enhanced corrosion protection and reduced galling in high-friction applications. The hex socket drive ensures reliable torque transmission in confined spaces, while the coarse thread pitch facilitates rapid installation in production environments.

Specification Summary & Compliance

This shoulder screw features Class 5g6g thread fit per ISO metric standards, ensuring precise thread engagement. The shoulder diameter maintains a tolerance of -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm for consistent performance. Manufactured to ISO 7379 specifications, it guarantees dimensional accuracy and interchangeability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting stringent environmental and safety standards for industrial use worldwide.
