• Enhanced corrosion protection with zinc plating that provides durable surface coverage for extended service life in harsh environments
• Precise dimensional compatibility with 15mm ID specifically engineered for M14 screw applications, ensuring perfect fit and optimal performance
• Exceptional mechanical strength from Rockwell C35 hardened steel construction that maintains tooth integrity under high clamping forces
• Reliable industrial performance backed by DIN 6797 certification, guaranteeing consistent quality and dimensional accuracy
• Environmental compliance assurance meeting both RoHS 3 and REACH standards for safe use in regulated industries
• Optimized load distribution with 24mm OD design that spreads pressure evenly while teeth provide positive locking action

Professional Applications & Engineering Value

This M14 external tooth lock washer delivers critical vibration-resistant fastening solutions for demanding industrial applications where joint integrity is paramount. Manufactured from zinc-plated steel with Rockwell C35 hardness, the washer's external teeth create multiple biting points that dig into both the bearing surface and fastener head, effectively resisting rotational loosening caused by machinery vibration, thermal cycling, and dynamic loading conditions. The metric dimensions (15mm ID × 24mm OD) ensure precise compatibility with M14 fasteners commonly used in heavy equipment, automotive assemblies, and structural frameworks. The zinc plating provides sacrificial corrosion protection, extending service life in environments exposed to moisture, chemicals, or temperature variations. This combination of mechanical locking action and environmental protection makes it ideal for applications requiring reliable, maintenance-free performance in vibration-prone assemblies.

Specification Summary & Compliance

This external tooth lock washer features precise metric dimensions with 15mm internal diameter, 24mm external diameter, and 0.9-1.2mm thickness range. Manufactured in compliance with DIN 6797 specifications for dimensional accuracy and performance requirements. The component demonstrates full compliance with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations concerning chemical safety. Constructed from zinc-plated steel hardened to Rockwell C35, ensuring consistent mechanical properties and tooth integrity across production batches for reliable industrial fastening applications.
