Professional Applications & Engineering Value
This M3 rounded head screw is engineered to address common industrial challenges such as vibration-induced loosening and corrosion in demanding applications. The combination of 18-8 stainless steel and a passivated finish provides exceptional resistance to rust and chemicals, making it suitable for machinery, electrical enclosures, and outdoor equipment. The integrated external-tooth lock washer bites into surfaces to maintain clamp load, preventing failures in high-vibration environments like automotive assemblies or conveyor systems. With a Phillips drive and coarse thread, it ensures quick, reliable installation, reducing labor costs and enhancing assembly integrity in metric-based industrial fastening projects.
Specification Summary & Compliance
This screw features a Class 6g thread fit for precise dimensional accuracy and a fully threaded M3 x 0.5 mm coarse thread design. It is manufactured in accordance with ASME B18.13.1M specifications and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industry-standard reliability.
