Professional Applications & Engineering Value
This M3 metric screw with a Phillips pan head and integrated external-tooth lock washer is engineered to address critical industrial challenges such as vibration-induced fastener failure and environmental degradation. The 18-8 stainless steel material, combined with a passivated finish, provides robust resistance to corrosion, making it ideal for applications in machinery, electronics, and outdoor equipment where moisture or chemicals are present. The coarse 0.5mm pitch thread and Class 6g fit ensure quick, reliable installation with minimal risk of stripping, while the lock washer enhances joint integrity in high-vibration settings like automotive assemblies or industrial motors. By offering 70,000 psi tensile strength and full threading, this screw delivers consistent clamping force and durability, reducing maintenance needs and downtime in industrial fastening systems.
Specification Summary & Compliance
This product features precise metric thread specifications with M3 size, 0.5mm pitch, and Class 6g thread fit for accurate dimensional compliance. It is manufactured in accordance with ASME B18.13.1M standards and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met for global industrial use.
