Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical challenges in precision machinery and industrial equipment. The 316 stainless steel material provides exceptional resistance to corrosion from chemicals, moisture, and salt, making it perfect for marine, chemical processing, and food-grade applications. The 40mm shoulder length acts as a precise pivot, spacer, or bearing surface, eliminating the need for additional components and reducing assembly time. Combined with the hex socket drive, it allows for high-torque installation in confined spaces, ensuring a secure fit that withstands operational vibrations. Its high tensile and shear strength ensures reliability in dynamic loads, while the Class 5g6g thread fit guarantees consistent engagement, minimizing the risk of thread stripping and improving overall assembly integrity in automated or manual production lines.

Specification Summary & Compliance

This metric shoulder screw features an M5x0.8 coarse thread with a Class 5g6g thread fit per ISO standards, ensuring precise dimensional accuracy. The shoulder diameter is manufactured to a tolerance of -0.072 to -0.01 mm, and the shoulder length tolerance is 0 to 0.25 mm, providing consistent performance. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial applications.
