Internal Tooth Lock Washers

An internal tooth lock washer is a type of lock washer used in fastening applications to prevent nuts and bolts from loosening due to vibration or external forces. Unlike standard split lock washers, internal tooth lock washers have serrated or toothed edges on the inner circumference of the washer. Here's how they work: Engage with the Nut or Bolt: When you place an internal tooth lock washer between a nut or bolt head and the surface being fastened, the toothed edges of the washer come into contact with the fastener itself. Resist Loosening: As the fastener is tightened, the teeth of the washer bite into the threads of the fastener, creating friction and resistance against rotation. This resists the tendency of the nut or bolt to loosen over time. Internal tooth lock washers are commonly used in applications where vibration or external forces could potentially cause fasteners to come loose. They are available in various sizes and materials to suit different needs and are widely used in industries such as manufacturing, construction, automotive, and machinery.
