Professional Applications & Engineering Value
This M4 shoulder screw with nylon patch locking technology addresses critical vibration-induced loosening challenges in industrial machinery and precision equipment. The 18-8 stainless steel construction combined with passivated finish provides exceptional corrosion resistance for harsh environments, while the precisely machined 8mm shoulder length ensures accurate component alignment in assemblies requiring rotational or linear motion control. The class 6g thread fit guarantees consistent engagement in metric applications, making it ideal for manufacturing equipment, automation systems, and precision instruments where vibration resistance and dimensional accuracy are paramount. The permanent thread locker maintains clamping force through thermal cycling from -70° to 250°F, eliminating the need for secondary locking components.
Specification Summary & Compliance
This precision shoulder screw features M4x0.7 coarse threading with Class 6g thread fit tolerance, 8mm shoulder length with tight dimensional tolerances, and 2.5mm hex drive socket. Manufactured from 18-8 stainless steel with passivated surface treatment, it delivers 70,000 psi tensile strength and Rockwell B55 hardness. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility while meeting industrial performance requirements for precision mechanical assemblies.
