Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. The 35mm shoulder length with minimal diameter tolerance ensures exact positioning of moving parts, reducing wear and improving operational accuracy in machinery, automation systems, and electronic enclosures. Made from 18-8 stainless steel, it offers excellent corrosion resistance, making it suitable for applications exposed to moisture, chemicals, or outdoor conditions. The hex socket head with knurling provides a secure grip during installation, preventing tool slippage and damage in high-torque scenarios. Combined with a coarse M5x0.8 thread and Class 5g6g fit, this fastener ensures reliable, vibration-resistant connections in demanding industrial settings, from conveyor systems to precision instruments.

Specification Summary & Compliance

This shoulder screw adheres to metric system standards with an M5 thread size, 0.8mm pitch, and coarse thread spacing. The shoulder diameter tolerance is -0.04 to -0.01mm, and shoulder length tolerance is 0 to 0.25mm, ensuring high dimensional accuracy. Threads conform to Class 5g6g fit for consistent engagement. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in regulated and environmentally conscious industries.
