During repairs in the garage or home workshop, it’s important to properly secure mechanical parts like thin sheet metals to prevent damage. One way to distribute a fastener’s load is by using a washer, which protects surfaces by spreading the force of a threaded fastener across a larger surface area. A fender washer is a flat washer with a large outer diameter relative to its center hole, which allows it to spread loads more effectively than standard flat washers. This makes fender washers ideal for use in auto-body repair, plumbing and electrical applications.
Unlike standard washers, fender washers have a greater outer diameter in relation to their inner diameter and are thicker than other types of flat washers. This allows them to be placed under the head of a screw or bolt and help distribute the forces applied during tightening. This feature makes them useful in auto-body, sheet metal and plumbing applications where it’s necessary to securely fasten parts made of soft or thin materials.
Fender washers are also useful when working with rusted or corroded parts. By placing a fender washer over the part’s pilot hole, it prevents the screw or bolt from directly making contact with the corroded surface and damaging it.
Boker’s offers fender washers in a wide range of sizes, with outside diameters from 0.081 inches to 5.000 inches and thicknesses up to.250 inch. These washers are available in metals including low-carbon steel, various spring steels and stainless steel, as well as non-metallic materials such as ABS, acetal, polyester and nylon MD. Some are even thru hardened, which increases their strength and protection by going through a process of heat-treating or carburizing. fender washers
