S-91106A137 15 mm ID x 24 mm OD DIN 6797 Internal-Tooth Lock Washers

Key Features & Benefits at a Glance

• Maximum vibration resistance through internal tooth design that bites into mating surfaces, preventing loosening under dynamic loads
• Enhanced corrosion protection with black-oxide steel coating, extending service life in demanding industrial environments
• Precision dimensional compatibility with M14 fasteners (15mm ID, 24mm OD) ensuring perfect fit and uniform load distribution
• Superior mechanical strength from Rockwell C35 hardened steel, maintaining tooth integrity under high clamping forces
• Guaranteed standardization through DIN 6797 certification, providing reliable performance across industrial applications
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industries
• Optimized thickness range (0.9-1.2mm) balancing flexibility for surface conformity with structural rigidity

Professional Applications & Engineering Value

This M14 internal tooth lock washer delivers critical vibration-resistant fastening solutions for industrial machinery, automotive assemblies, and heavy equipment where dynamic loads cause conventional washers to fail. The black-oxide steel construction provides essential corrosion resistance while the precisely engineered internal teeth create permanent biting action into both bolt head and workpiece surfaces. Engineered to DIN 6797 standards, these metric lock washers maintain consistent locking force in high-vibration environments, preventing costly downtime from fastener loosening. The Rockwell C35 hardness ensures teeth retain their biting capability through repeated torque cycles, making them ideal for permanent installations requiring reliable vibration-resistant performance.
