Professional Applications & Engineering Value
This M12 shoulder screw in 316 stainless steel is engineered to address critical alignment and corrosion challenges in industrial assemblies. The metric socket head with 8 mm hex drive and knurled texture provides secure, high-torque installation, reducing tool slippage in confined spaces. Its 30 mm shoulder length and precise diameter tolerance offer stable bearing surfaces for rotating parts, minimizing wear in machinery, conveyor systems, and precision instruments. The Class 5g6g thread fit and coarse M12x1.75 threads ensure quick assembly and vibration resistance, while the material's inherent corrosion resistance extends service life in marine, chemical, and food processing applications. Complying with ISO 7379, this fastener delivers reliable performance where dimensional accuracy and structural integrity are paramount.
Specification Summary & Compliance
This shoulder screw features M12x1.75 coarse metric threads with a Class 5g6g thread fit for standard tolerance. The shoulder diameter is 16 mm with a tolerance of -0.072 to -0.01 mm, and shoulder length is 30 mm with a 0 to 0.25 mm tolerance. It meets ISO 7379 specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) for environmental safety.
