Professional Applications & Engineering Value
This M2 shoulder screw in 316 Stainless Steel is engineered to address critical challenges in precision machinery, electronics, and automation systems. The 4mm shoulder diameter and 10mm shoulder length provide exact alignment for rotating parts, reducing wear and misalignment in assemblies. The socket head with hex drive and knurled texture ensures secure tool engagement, minimizing cam-out during high-torque installation. With Class 5g6g thread fit and coarse pitch, it offers rapid assembly and reliable performance in vibrating environments. Its corrosion-resistant properties make it suitable for chemical processing, medical devices, and outdoor equipment, where durability and compliance with RoHS and REACH standards are essential for operational safety and longevity.
Specification Summary & Compliance
This shoulder screw features a metric M2 x 0.4mm coarse thread with Class 5g6g tolerance for precise fit. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring dimensional accuracy. Manufactured from 316 Stainless Steel with Rockwell B79 hardness, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and suitability for industrial applications requiring high tensile and shear strength.
