The Hidden Dangers of Reusing External Tooth Lock Washers

 

It’s tempting to reuse hardware components, but doing so with External Tooth Lock Washers can be a costly mistake. Once the teeth of the washer bite into the metal surface during tightening, their shape and tension are permanently altered. Reusing them compromises the bite force and reduces vibration resistance, leading to loose bolts or equipment failure.
Always inspect your External Tooth Lock Washers before reinstallation. If the teeth are flattened, bent, or corroded, replace them immediately. In high-vibration applications like engines or heavy machinery, new washers ensure maximum grip and prevent dangerous loosening over time. Investing in fresh, high-quality washers during maintenance keeps your assemblies reliable and compliant with safety standards.
