Professional Applications & Engineering Value

This precision M2 shoulder screw delivers exceptional engineering value in applications requiring exact component positioning and reliable fastening. The 18-8 stainless steel construction with passivated finish provides excellent corrosion resistance for machinery, electronics, and automotive assemblies exposed to moisture or chemicals. The precisely machined 3mm shoulder diameter with tight tolerances ensures perfect alignment of moving parts in precision instruments, while the 7mm shoulder length maintains consistent spacing in stacked assemblies. The low-profile socket head design allows installation in space-constrained applications without compromising torque capability. With Class 6g thread fit and coarse 0.4mm pitch, these metric shoulder screws offer quick assembly and vibration resistance in automated manufacturing environments, reducing maintenance cycles and improving production efficiency.

Specification Summary & Compliance

This precision fastener features Class 6g thread fit per metric standards with exact shoulder dimensions (3mm diameter with -0.025 to 0mm tolerance, 7mm length with 0 to 0.05mm tolerance) for precise mechanical assemblies. Manufactured from 18-8 stainless steel with passivated finish and right-hand coarse thread spacing (0.4mm pitch). The screw complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors while maintaining consistent mechanical properties including Rockwell B90 hardness and 85,000 psi tensile strength.
