Professional Applications & Engineering Value

This M12 shoulder screw is engineered to address critical alignment and load-bearing challenges in industrial assemblies. The 18-8 stainless steel material offers excellent resistance to corrosion and oxidation, making it suitable for applications in machinery, automotive, and outdoor equipment where exposure to moisture and chemicals is common. The 20mm shoulder diameter and precise length provide a stable bearing surface, preventing lateral movement and ensuring accurate positioning of components like gears, pulleys, and linkages. Combined with the hex socket drive and coarse metric thread, it allows for high-torque installation and rapid assembly, reducing downtime in production lines. Its high tensile and shear strength ensures durability in dynamic or high-stress environments, providing long-term reliability and reducing the risk of fastener failure.

Specification Summary & Compliance

This shoulder screw features a Class 5g6g thread fit per metric standards, ensuring precise thread engagement and tolerance. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, providing tight dimensional control. It is manufactured in accordance with ISO 7379 specifications for consistent quality and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its safety and sustainability for global industrial use.
