Professional Applications & Engineering Value

The M5 shoulder screw engineered from alloy steel with zinc plating addresses critical industrial fastening challenges where precision alignment and corrosion resistance are paramount. The integrated 4mm shoulder serves as a precise locating diameter in machinery, automation systems, and precision instruments, eliminating the need for additional spacing components. The low socket head profile with dual drive options (socket and slotted) provides installation flexibility in confined spaces while maintaining tool accessibility. This DIN 923 compliant fastener is particularly valuable in assembly applications requiring exact component positioning, such as in bearing retention, gear assemblies, and pivoting mechanisms, where the shoulder prevents axial movement and maintains concentricity. The coarse thread configuration ensures rapid installation and reliable performance in various materials, making it ideal for high-volume production environments.

Specification Summary & Compliance

This precision shoulder screw features M5x0.8 metric coarse threads with Class 6g tolerance for consistent fit. The shoulder maintains precise dimensions with diameter tolerance of -0.036mm to 0mm and length tolerance of 0.07mm to 0.15mm. Manufactured to DIN 923 specifications and compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring suitability for regulated industrial applications worldwide.
