A Big OD Washer DIN 9021, also known as a large outer diameter or fender washer, is designed to provide a wider bearing surface under the head of a bolt or nut. Its increased outer diameter helps distribute load more evenly, prevents pull-through, and protects softer or oversized holes from damage.

Big OD Washers are widely used across industries including construction, machinery manufacturing, automotive, infrastructure, engineering, and household applications. Their robust design makes them ideal for applications requiring improved load spreading and enhanced fastening reliability.
