External Tooth Lock Washers

An external tooth lock washer is a type of lock washer used in fastening applications to prevent nuts and bolts from loosening due to vibration or other external forces. Unlike standard split lock washers, external tooth lock washers have serrated or toothed edges on the outer circumference of the washer. Here's how they work: Bite into Material: When you place an external tooth lock washer between a nut or bolt head and the surface being fastened, the toothed edges of the washer come into contact with both the fastener and the material. Resist Loosening: As the fastener is tightened, the teeth of the washer bite into the material and the fastener itself, creating friction and resistance against rotation. This resists the tendency of the nut or bolt to loosen over time. External 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.
