Professional Applications & Engineering Value
This M5 pan head screw with external-tooth lock washer is engineered to address common industrial challenges such as vibration-induced fastener failure and corrosion in demanding settings. Constructed from 18-8 stainless steel with a passivated finish, it resists rust and chemical exposure, making it suitable for machinery, automotive assemblies, and outdoor equipment. The external-tooth lock washer bites into surfaces to maintain clamp force, preventing back-off in high-vibration environments like motors or conveyors. With a Phillips drive and fully threaded metric coarse thread, it offers quick installation and robust holding power, ensuring reliable performance in industrial fastening applications where security and durability are critical.
Specification Summary & Compliance
This screw features M5 x 0.8mm coarse threads with a Class 6g tolerance for precise fit, and is fully threaded over a 10mm length. It meets JIS B 1188-C specifications for dimensional accuracy and performance, and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for various industrial uses.
