Professional Applications & Engineering Value

This M12 shoulder screw is engineered to address critical challenges in precision machinery and industrial equipment. The 316 stainless steel material offers excellent resistance to corrosion and chemicals, making it suitable for applications in manufacturing, automotive, and marine sectors where exposure to moisture is common. The 60mm shoulder length with minimal tolerances provides a stable pivot or bearing surface, reducing wear and misalignment in assemblies like linkages, gears, and rotating components. The knurled socket head design enhances grip during installation, preventing tool slippage and ensuring consistent torque application. By integrating a Class 5g6g thread fit and coarse thread pitch, this screw delivers reliable fastening in high-vibration environments, minimizing the risk of loosening and maintenance downtime. Ideal for precision shoulder bolts in automated systems, this component supports long-term durability and efficiency in B2B operations.

Specification Summary & Compliance

This shoulder screw adheres to ISO 7379 standards, ensuring dimensional accuracy with a shoulder diameter tolerance of -0.072 to -0.01 mm and length tolerance of 0 to 0.25 mm. The M12x1.75 metric thread follows a Class 5g6g fit for precise engagement, while the right-hand thread direction and coarse spacing facilitate easy assembly. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) confirms environmental safety, supporting use in regulated industries without hazardous substances.
