Professional Applications & Engineering Value
This M4 shoulder screw is engineered to address critical alignment and load-bearing challenges in precision assemblies. The 18-8 stainless steel material provides excellent resistance to corrosion and oxidation, making it suitable for industrial machinery, automotive components, and electronic enclosures exposed to moisture or chemicals. The black oxide finish not only enhances aesthetic appeal but also adds a protective layer that reduces friction and galling during repeated use. With a 15mm shoulder length and precise diameter tolerance, it acts as a reliable pivot or spacer, preventing misalignment in rotating parts and reducing stress on threaded sections. The coarse pitch metric thread and hex socket drive facilitate quick, secure fastening in high-vibration environments, ensuring long-term operational stability and minimizing downtime for maintenance.
Specification Summary & Compliance
This shoulder screw adheres to ISO 7379 specifications, with a thread fit of Class 5g6g and shoulder diameter tolerance of -0.072 to -0.01 mm for dimensional accuracy. It is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material sustainability in industrial applications.
