Professional Applications & Engineering Value
This M3 shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. The 18-8 stainless steel material provides excellent resistance to oxidation and chemical exposure, making it suitable for electronics, machinery, and automotive components where environmental factors are a concern. The 4mm shoulder diameter with precise tolerances acts as a reliable pivot or spacer, eliminating misalignment in rotating parts like gears and pulleys. Combined with the Class 6g thread fit and coarse 0.5mm pitch, it ensures quick, secure fastening without stripping, reducing assembly time and maintenance needs in high-vibration settings. The socket head design allows for compact installations where space is limited, enhancing the screw's versatility across various industrial applications.
Specification Summary & Compliance
This shoulder screw adheres to metric system standards with an M3 thread size, 0.5mm coarse pitch, and Class 6g thread fit per ISO tolerance guidelines. The shoulder diameter is manufactured to -0.025 to 0mm tolerance, and the shoulder length to 0 to 0.05mm tolerance, ensuring precise fit in assemblies. It is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, confirming its suitability for regulated industries and international markets.
