Professional Applications & Engineering Value

This M3 shoulder screw is engineered from 316 stainless steel to address critical challenges in industrial settings, such as corrosion from chemicals or moisture. The 35mm shoulder length provides a precise pivot or spacer in assemblies, minimizing misalignment and reducing wear on moving parts in machinery, automation systems, and electronic enclosures. With a coarse thread pitch of 0.5mm and Class 5g6g thread fit, it ensures quick, secure fastening that resists loosening under vibration. The knurled socket head and 2mm hex drive enhance torque application, making it ideal for applications requiring repeated adjustments or high-torque installation without stripping. This combination of corrosion resistance, strength, and precision supports reliable performance in sectors like manufacturing, automotive, and marine engineering.

Specification Summary & Compliance

This shoulder screw adheres to metric system standards with an M3x0.5 thread size and pitch, featuring a Class 5g6g thread fit for dimensional accuracy. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring consistent fit in precision assemblies. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial applications without hazardous substances.
