- Enhanced corrosion protection through zinc-plated steel construction for extended service life in harsh environments
- Precision dimensional compliance with DIN 6797 standards ensuring perfect fit for M10 fastener applications
- Exceptional hardness rating of Rockwell C42 maintains tooth integrity and locking performance under high stress
- Optimized size compatibility with 10.5mm ID and 18mm OD providing ideal bearing surface for M10 screws
- Regulatory compliance assurance meeting RoHS 3 and REACH requirements for global industrial applications
- Reliable anti-rotation performance through internal tooth design that prevents both rotation and axial movement
Professional Applications & Engineering Value
These M10 tooth lock washers engineered to DIN 6797 standards provide critical vibration-resistant fastening solutions for demanding industrial applications. The zinc-plated steel construction offers excellent corrosion resistance while maintaining the Rockwell C42 hardness necessary for the internal tooth design to effectively bite into mating surfaces. This combination solves common engineering challenges in machinery, automotive assemblies, and electrical enclosures where vibration-induced loosening can lead to equipment failure. The precise 10.5mm internal diameter and 18mm outer diameter ensure proper fitment while the controlled 0.8-1.0mm thickness maintains optimal spring tension for persistent locking action throughout the fastener's service life.
Specification Summary & Compliance
Manufactured to DIN 6797 specifications with precise dimensional tolerances for M10 fastener applications. Features internal tooth location design with 10.5mm ID, 18mm OD, and 0.8-1.0mm thickness range. Constructed from zinc-plated steel with Rockwell C42 hardness rating. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors and international markets.
