Professional Applications & Engineering Value

This M2 shoulder screw is engineered to address critical alignment and fastening challenges in precision assemblies. The 316 stainless steel material provides exceptional resistance to corrosion from chemicals, moisture, and salt spray, making it perfect for medical devices, food processing equipment, and marine applications. The integrated 3mm shoulder diameter acts as a precise pivot or bearing surface, eliminating the need for separate spacers and reducing component count. Combined with the Class 5g6g coarse thread and hex socket drive, it ensures quick, secure installation with high torque resistance, preventing loosening in vibrating environments. The 22mm shoulder length offers ample support for rotating parts or linkages, enhancing the durability and reliability of machinery and electronic enclosures.

Specification Summary & Compliance

This shoulder screw conforms to metric (M2 x 0.4mm) coarse thread standards with a Class 5g6g thread fit for consistent engagement. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring high dimensional accuracy. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, affirming its suitability for regulated industrial and consumer goods.
