Professional Applications & Engineering Value

This M4 shoulder screw combines the convenience of manual operation with precision engineering for demanding industrial applications. The 18-8 stainless steel construction provides excellent corrosion resistance in harsh environments, while the knurled thumb head ensures secure grip during frequent adjustments. The 14mm shoulder length with precise diameter control enables accurate component positioning in assemblies, eliminating misalignment issues. With Class 6g thread fit and coarse M4 x 0.7mm metric thread, this fastener delivers reliable performance in machinery, electronics, and precision equipment where repeated disassembly is required. The combination of thumb screw convenience and shoulder screw precision makes it ideal for applications requiring both easy manual operation and exact component spacing.

Specification Summary & Compliance

This precision shoulder screw features Class 6g thread fit with M4 x 0.7mm coarse metric threads and right-hand thread direction. The shoulder maintains precise dimensions with 5mm diameter (-0.025 to 0 mm tolerance) and 14mm length (0 to 0.05 mm tolerance) for accurate alignment. Manufactured from 18-8 stainless steel with Rockwell B83 hardness and 70,000 psi tensile strength. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for industrial applications.
