DIN 9021 Flat Washer Large Series
DIN 9021 large-series flat washer made of zinc-plated steel. It reduces pressure on the working surface in construction, engineering and auto body repair.
DIN 9021 washer is a large-series flat washer, a mounting element for reinforcing a fastening joint. Used in auto body repair, where it is also called a body washer.
In construction and mechanical engineering, the washer is used to reduce pressure on the working surface. The increased outer diameter allows it to be used with less durable materials: it reduces deflection and the risk of the metric fastener pulling through the bearing surface.
The washer has a ring shape. It is made of high-strength steel with a zinc-plated coating that protects against corrosion. It is one of the most common fastening elements, used together with other fastening products.
