Professional Applications & Engineering Value

This precision shoulder screw addresses critical alignment and space constraints in demanding industrial applications. The 18-8 stainless steel construction with passivated finish provides exceptional corrosion resistance for machinery exposed to moisture, chemicals, or outdoor elements. The precisely machined 5mm shoulder diameter with tight tolerances ensures accurate component positioning in assemblies, eliminating misalignment issues in precision equipment, automated systems, and optical devices. The low profile socket head design is particularly valuable in compact electronic enclosures, medical devices, and instrumentation where clearance is limited. With Class 6g thread fit and M2 x 0.4mm coarse thread pitch, installation is streamlined while maintaining secure fastening in vibration-prone environments. These metric shoulder screws deliver engineering reliability for applications requiring both precise alignment and corrosion resistance.
