What is fender washer?

A fender washer is a type of flat washer that has a larger outer diameter than standard washers, providing greater surface area. It is typically used to distribute the load of a fastener over a larger area, which can prevent damage to thin materials or help secure components in place. Fender washers are often made of metal or plastic and are commonly used in construction, automotive, and electrical applications. Their design helps to improve stability and reduce the risk of the fastener pulling through the material.
