Professional Applications & Engineering Value
This M6 external tooth lock washer is engineered to solve critical fastening challenges in high-vibration environments. The zinc-plated steel construction provides a robust barrier against corrosion, which is essential for automotive, machinery, and general industrial applications where exposure to moisture and chemicals is common. The external teeth design ensures a firm grip, effectively resisting rotational loosening caused by vibrations and thermal cycling. This makes it an indispensable component for securing M6 screws in engines, heavy equipment, and structural assemblies, enhancing the reliability and safety of the entire system by maintaining clamp load and preventing joint failure.
Specification Summary & Compliance
This washer conforms to the dimensional and performance requirements of the DIN 6798 standard. Key specifications include an Internal Diameter (ID) of 6.4 mm, Outer Diameter (OD) of 11 mm, and a Thickness of 0.7-0.8 mm, designed for use with M6 screw sizes. The material is zinc-plated steel with a hardness of Rockwell C35. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for use in various global markets.
