• Enhanced durability provided by Rockwell C42 hardness, maintaining tooth integrity and locking performance over repeated use
• Reliable corrosion protection from zinc-plated steel construction, suitable for industrial environments
• Precise metric fit with 15mm ID and 24mm OD, ensuring compatibility with M14 screws and consistent assembly
• Standardized performance per DIN 6797, guaranteeing dimensional accuracy and functional reliability
• Environmental compliance with RoHS 3 and REACH, meeting strict regulatory requirements for safe usage
• Optimized internal tooth design that minimizes surface marring while providing effective locking action

Professional Applications & Engineering Value

This M14 internal tooth lock washer delivers critical vibration resistance in demanding applications where fastener security is paramount. Manufactured from zinc-plated steel, it offers both corrosion resistance and the mechanical strength needed to maintain clamp load in high-vibration environments such as machinery, automotive assemblies, and heavy equipment. The internal tooth location concentrates locking force directly under the screw head, biting into surfaces without excessive damage while preventing rotational loosening. Engineers specify this DIN 6797 compliant washer for its predictable performance in preventing catastrophic fastener failure, reducing maintenance frequency, and ensuring operational safety in industrial applications where reliability cannot be compromised.

Specification Summary & Compliance

This washer meets DIN 6797 specifications with precise dimensions: 15mm internal diameter, 24mm outer diameter, and 0.9-1.2mm thickness for M14 screw size. Manufacturing follows standardized tolerances for consistent fit and function. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance in global markets.
