M10 Internal Tooth Lock Washers | Flange Anti-Loosening - HighFasteners

Product Overview

The M10 Internal Tooth Lock Washer features inward-facing teeth that grip fastener heads and equipment flanges to generate strong anti-slip friction. This prevents loosening under vibration and operational stress, ensuring stable, long-term connections.

Ideal for securing flanges in heavy machinery, pumps, motors, and industrial equipment requiring reliable performance.

Key Features:

Superior Anti-Loosening: Internal teeth bite into fastener head and flange for maximum friction and vibration resistance.

Flange Security: Specifically designed to lock against flange surfaces for stable equipment mounting.

Corrosion Resistant: High-quality material with protective finish for durability in demanding environments.
