Professional Applications & Engineering Value
This 316 Stainless Steel shoulder screw is engineered to address critical challenges in precision assemblies, such as misalignment and corrosion-induced failure. The M4 coarse thread and 10mm thread length provide robust fastening in dynamic environments, while the smooth hex socket head allows for high-torque installation without stripping. The 6mm shoulder diameter acts as a precise pivot or spacer in machinery, automotive, and electronics, reducing part wear and maintenance costs. Its corrosion-resistant properties make it suitable for marine, chemical processing, and food industry applications, ensuring long-term reliability and compliance with international standards like RoHS and REACH.
Specification Summary & Compliance
This shoulder screw features a Class 5g6g thread fit per metric standards, ensuring dimensional accuracy for the M4x0.7 coarse thread. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, supporting precise engineering requirements. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally sensitive and industrial applications without hazardous substances.
