Why External Tooth Lock Washers Stand Out

External Tooth Lock Washers feature multiple sharp teeth along their outer edge, which bite into both the fastener and the mounting surface. This creates friction that prevents rotation, even under constant vibration. Unlike Spring Lock Washers that rely on spring tension, these washers provide maximum grip and improved electrical conductivity, making them ideal for grounding applications.

Key benefits include excellent performance in high-vibration environments, suitability for soft materials like aluminum or plastic, and long-term corrosion resistance when made from stainless steel washers. Industries such as aerospace, defense, heavy machinery, and electronics rely on External Tooth Lock Washers for secure fastening. Trusted shim washer manufacturers supply these washers alongside other industrial washers like tab washers, sealing washers, and conical washers, ensuring reliable, high-performance solutions for demanding applications.
