Professional Applications & Engineering Value
These M2.5 shoulder screws are engineered to address critical alignment and durability challenges in precision assemblies. The 18-8 stainless steel material provides excellent resistance to corrosion and oxidation, making them suitable for applications in electronics, automotive, and machinery where exposure to moisture or chemicals is common. The hex socket head design allows for compact installation in confined spaces, while the precise shoulder with minimal tolerances ensures accurate component positioning and reduces wear on mating parts. With a Class 6g thread fit and coarse pitch, these screws facilitate quick assembly and maintain secure fastening in high-vibration environments, enhancing overall system reliability and reducing maintenance needs.
Specification Summary & Compliance
This shoulder screw features a Class 6g thread fit per metric standards, with a shoulder diameter tolerance of -0.025 to 0 mm and shoulder length tolerance of 0 to 0.05 mm for high precision. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material sustainability in industrial use.
