About External Star Washers

External star washers are designed with a series of pointed teeth or prongs that extend outward from the center. These teeth dig into the surface of the material being fastened, creating a locking effect that helps prevent the fastener from loosening due to vibration or dynamic loads. External star washers provide excellent grip and resistance, making them ideal for applications where secure and stable connections are crucial.

At Teshi Fasteners, our external star washers are manufactured with precision from high-quality materials to ensure exceptional performance and longevity. Available in materials such as carbon steel, stainless steel, and alloy steel, our washers meet various industry standards and specifications.
