Professional Applications & Engineering Value

This M3 shoulder screw is engineered to address common industrial challenges such as component misalignment, corrosion-induced failure, and assembly inefficiency. The 316 Stainless Steel material offers excellent resistance to corrosive agents, making it suitable for marine, chemical processing, and food-grade equipment. The hex socket drive combined with a knurled head ensures secure tool engagement, reducing installation time and preventing damage to the fastener. The precisely machined shoulder with an 8 mm length provides a stable bearing surface for rotating parts like gears and pulleys, minimizing friction and extending service life. With its coarse pitch thread and high tensile strength, it delivers reliable clamping force in automated machinery, electronics, and precision instruments, enhancing overall system durability and performance.

Specification Summary & Compliance

The screw features a Class 5g6g thread fit per metric standards, ensuring dimensional accuracy and interchangeability. The shoulder diameter tolerance is controlled between -0.072 to -0.01 mm, and the shoulder length tolerance is 0 to 0.25 mm for precise assembly. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances and supporting environmentally responsible manufacturing practices.
