S-93925A290 10.5 mm ID x 18 mm OD DIN 6797 Internal-Tooth Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance with internal teeth that bite into mating surfaces, preventing loosening under dynamic loads
• Excellent corrosion resistance from 18-8 stainless steel construction, ensuring long-term reliability in harsh environments
• Precision DIN 6797 compliance guarantees dimensional accuracy and consistent performance in metric fastener systems
• Optimized for M10 screw applications with 10.5mm ID for perfect fit and maximum locking efficiency
• Durable 0.8-1.0mm thickness provides optimal spring action while maintaining material integrity
• Environmental compliance assurance with RoHS 3 and REACH standards for global industrial use
• Internal tooth design concentrates locking force directly under screw head for secure fastening

Professional Applications & Engineering Value

Engineered to solve critical vibration-induced loosening in industrial machinery, automotive assemblies, and heavy equipment, these M10 internal tooth lock washers deliver exceptional vibration resistance through their specialized tooth configuration. The 18-8 stainless steel material provides inherent corrosion resistance, making them ideal for applications exposed to moisture, chemicals, or outdoor elements. Unlike standard flat washers, the internal tooth location creates multiple biting points that dig into both the fastener and workpiece, maintaining clamp load integrity even under extreme vibration conditions. This DIN 6797 compliant design ensures precise dimensional control for reliable performance in metric fastener systems, offering engineers a proven solution for critical joint security where failure is not an option.

Specification Summary & Compliance

Manufactured to DIN 6797 standards with precise dimensional tolerances: 10.5mm internal diameter, 18mm outer diameter, and 0.8-1.0mm thickness range. The internal tooth lock washer design follows established engineering specifications for optimal performance in M10 screw applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and global market acceptance. Material certification confirms 18-8 stainless steel composition for consistent mechanical properties and corrosion resistance.
