Star washers are a specific type of washer designed to increase locking force by resisting torque applied by the nut, preventing it from unscrewing or separating. Featuring either internal or external tabs, star washers offer greater application suitability. Internal tabs run along the inside diameter, while external options have tabs located on the outer diameter for superior locking capabilities—making them ideal for applications that require continuous reliability.
