Professional Applications & Engineering Value
This M6 shoulder screw is engineered to address common challenges in precision assembly, such as component misalignment and rotational friction. The 18-8 stainless steel material offers outstanding corrosion resistance, making it ideal for applications in humid or chemically aggressive environments, including machinery, automotive systems, and electronic enclosures. The 40mm shoulder length acts as a precise pivot or spacer, minimizing wear on connected parts and ensuring smooth operation. Combined with the knurled hex socket head, it allows for secure, high-torque installation without slippage, enhancing assembly efficiency. Its metric thread and ISO 7379 compliance ensure interoperability in global supply chains, reducing downtime and maintenance costs.
Specification Summary & Compliance
This shoulder screw features precise dimensional tolerances, including a shoulder diameter of 8 mm with a tolerance of -0.072 to -0.01 mm and a shoulder length of 40 mm with a tolerance of 0 to 0.25 mm. The thread fit conforms to Class 5g6g per metric standards, ensuring reliable engagement. It is manufactured in accordance with ISO 7379 and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting environmentally conscious and safe industrial practices.
