Internal & External Tooth Lock Washers

About Internal & External Tooth Lock Washers

Internal and external tooth lock washers are mechanical fasteners designed to prevent loosening of nuts and bolts due to vibrations or dynamic loads. The internal tooth lock washer features internal serrations, creating friction between the washer and the fastener, enhancing grip. In contrast, the external tooth lock washer has external serrations to engage with the surface it contacts, providing stability. Both washers distribute pressure evenly, reducing the risk of bolt or nut rotation. These lock washers are crucial in applications where maintaining tight connections is essential for safety and operational integrity, such as automotive, aerospace, and machinery industries.
