Lock washers with external teeth, also known as external tooth lock washers or external serrated lock washers, are a type of fastener used to prevent loosening or rotation of bolts, screws, or other threaded fasteners.

These washers have serrations or teeth on the outer edge, which bite into the mating surface or the underside of the fastener head when tightened. This creates friction and helps to prevent the fastener from loosening due to vibrations or other forces.

The external teeth on these washers are designed to dig into the material, providing a more secure grip compared to regular flat washers. They are commonly used in applications where there is a risk of fastener loosening, such as automotive, machinery, or construction industries.

Lock washers with external teeth are typically made from materials like steel, stainless steel, or other metal alloys. They are available in various sizes and can be used with different types of fasteners, depending on the specific requirements of the application.
