Professional Applications & Engineering Value
This M4 shoulder screw with nylon patch locking technology addresses critical vibration-induced loosening in precision assemblies. The 18-8 stainless steel construction combined with passivated finish provides exceptional corrosion resistance for harsh industrial environments. The hex socket drive enables high torque application in confined spaces, while the precisely machined shoulder diameter and Class 6g thread fit ensure accurate component alignment in machinery, automation systems, and precision instruments. The coarse thread pitch facilitates quick assembly while maintaining the integrity of metric thread standards, making it ideal for applications requiring reliable positioning and vibration resistance.
Specification Summary & Compliance
Manufactured to precise metric specifications with Class 6g thread fit tolerance, this shoulder screw features a 5mm shoulder diameter with -0.025 to 0 mm tolerance and 6mm shoulder length with 0 to 0.05 mm tolerance. The fastener complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications. The combination of precise shoulder fit and standardized metric thread specifications guarantees consistent performance in demanding engineering environments.
