External tooth lock washers are essential for applications where fasteners are subject to vibration or movement. The sharp teeth create a mechanical lock that maintains proper tension and prevents hardware from backing out over time. The 410 stainless steel material offers good corrosion resistance for saltwater and freshwater environments.
