Professional Applications & Engineering Value
These M18 tooth lock washers deliver critical vibration-resistant performance in demanding industrial applications where fastener security is paramount. The zinc-plated steel construction provides essential corrosion protection while maintaining the mechanical strength needed for heavy machinery, automotive assemblies, and structural frameworks. The internal tooth location ensures maximum biting action directly against the fastener head or nut surface, creating superior resistance to rotational loosening caused by equipment vibration or thermal cycling. Engineered to DIN 6797 standards, these metric lock washers offer reliable performance in European equipment and global manufacturing applications requiring precise dimensional compliance and consistent locking force.
Specification Summary & Compliance
This tooth lock washer features precise dimensional specifications with 19mm inner diameter, 30mm outer diameter, and 1.2-1.5mm thickness range. Manufactured to DIN 6797 standards with Rockwell C42 hardness for optimal mechanical properties. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors with restricted substance requirements.
