Professional Applications & Engineering Value

This M4 shoulder screw delivers exceptional value in precision assembly applications where alignment accuracy and manual accessibility are critical. The 18-8 stainless steel construction provides excellent corrosion resistance for machinery, electronic enclosures, and automotive components exposed to moisture or chemicals. The knurled thumb head combined with hex drive allows engineers to achieve secure fastening without specialized tools, significantly reducing installation time in maintenance operations or prototype development. The precisely manufactured shoulder diameter (5mm) and length (4mm) create stable bearing surfaces for rotating components, spacers, and linkages, eliminating misalignment issues that can cause premature wear. The Class 6g thread fit ensures consistent engagement with mating parts while the coarse 0.7mm pitch facilitates rapid assembly in production environments.

Specification Summary & Compliance

This precision metric shoulder screw features M4x0.7mm coarse right-hand threads with Class 6g thread fit per ISO metric standards. Shoulder dimensions maintain tight tolerances with diameter controlled at -0.025 to 0 mm and length at 0 to 0.05 mm for precise shoulder fit. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material transparency for industrial applications worldwide.
