Professional Applications & Engineering Value

This M2 shoulder screw in 316 stainless steel is engineered to address critical alignment and corrosion challenges in precision assemblies. The 18mm shoulder length provides a stable bearing surface for rotating parts, reducing wear in machinery, while the Class 5g6g thread fit and coarse M2 x 0.4mm thread ensure rapid assembly with minimal cross-threading risk. The knurled socket head and 2mm hex drive allow for high-torque installation in confined spaces, making it ideal for electronics, automotive sensors, and medical devices where high tensile strength and chemical resistance are paramount. Its compliance with international standards guarantees reliability in global supply chains.

Specification Summary & Compliance

This precision metric shoulder screw features a Class 5g6g thread fit per ISO standards, with shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm for consistent dimensional accuracy. Manufacturing adheres to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and material traceability.
