Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical alignment and durability challenges in industrial applications. The 316 stainless steel material provides excellent resistance to corrosion, making it suitable for use in moist or chemically aggressive environments, such as marine equipment or chemical processing machinery. The black oxide finish adds an extra layer of protection against oxidation while reducing light reflection. The integrated 8mm shoulder acts as a precise pivot or spacer, minimizing misalignment and wear in moving parts like bearings, linkages, and gears. With a hex socket head, it allows for high-torque installation in confined spaces, ensuring secure fastening without protruding elements. This combination of precision metrics and robust construction delivers long-term reliability, reducing maintenance needs and downtime in heavy-duty assemblies.

Specification Summary & Compliance

This metric shoulder screw features an M5x0.8 coarse thread with Class 5g6g thread fit for precise tolerance. The shoulder diameter is 6 mm with a tolerance of -0.072 to -0.01 mm, and the shoulder length is 8 mm with a tolerance of 0 to 0.25 mm, ensuring accurate fit in assemblies. Manufactured to high standards, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for industrial and international markets.
