• Precise dimensional compatibility with 17mm ID and 26mm OD ensuring perfect fit for M16 screw applications
• Exceptional hardness durability with Rockwell C35 rating maintaining tooth integrity and locking performance under repeated stress
• Reliable standardization compliance meeting DIN 6797 specifications for consistent quality and interchangeability
• Environmental regulation adherence with RoHS 3 and REACH compliance for safe use across global markets
• Optimized thickness range (1.0-1.4mm) providing ideal spring tension while accommodating surface variations

Professional Applications & Engineering Value

This M16 internal tooth lock washer delivers critical vibration resistance in demanding applications where conventional fasteners fail. The black-oxide steel construction provides essential corrosion protection while the precisely engineered internal teeth create multiple biting points that dig into both the bearing surface and fastener head. This dual-action locking mechanism solves the common industrial problem of joint loosening in automotive assemblies, heavy machinery, and vibrating equipment. The Rockwell C35 hardness ensures the teeth maintain their sharp biting edges through numerous installation cycles, while the metric dimensions guarantee perfect compatibility with M16 fasteners in European-engineered equipment. By meeting DIN 6797 standards, this washer provides engineers with predictable performance and reliable vibration-proof security in critical connections.
