Professional Applications & Engineering Value
These M10 external tooth lock washers solve critical vibration-induced loosening problems in industrial machinery, automotive assemblies, and electrical enclosures. The zinc-plated steel construction provides sacrificial corrosion protection while the external teeth create positive locking action by embedding into both the fastener and workpiece. The 90° countersunk design allows seamless integration with countersunk screw heads, eliminating protrusions in precision applications. Engineered to DIN 6798 standards, these metric washers deliver predictable performance in high-vibration environments where traditional flat washers fail, significantly reducing maintenance frequency and assembly failures.
Specification Summary & Compliance
Manufactured to DIN 6798 specifications with dimensional accuracy including 10.5mm ID, 19mm OD, and 0.45-0.55mm thickness. Features external tooth location and 90° countersink angle for M10 screw applications. Hardness maintained at Rockwell C35 for consistent performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe usage across industrial sectors.
