Dock Flat Washer, Steel, Black Oxide, Round Shape, USA Made, 0.938" ID, 3.000" OD, 0.250" Thick (Pack of 5)

Fender Flatwashers were named because of their original use in auto body repair. The large outer diameter covered up a lot of area, and also spread the load across a wide area of thin sheet metal. In todays world these washers are used in electrical, construction, HVAC, and general industrial applications. The purpose of a washer is to spread the load from the head of the bolt across a wider area than the bolt head, which increases the strength of the joint. Fender washers do this well because the outer diameter is so much larger than the diameter of a standard flat washer. These extra thick Fender washers are manufactured in Steel Zinc, 18-8 Stainless Steel, and Type 316 Stainless Steel. The increased thickness provides superior strength, as the thicker the washer, the stronger it gets.

Made in the USA. These flat washers are produced in the USA for excellent quality conformance. One of the significant differences between less expensive imported products and ours are the way we stamp. Many cheap imports are produced on gang dies that produce 10 or more washers per stroke of the press. Using such a large die means that the individual washer sets are not adjustable - when the punch wears, the dimensions change and there is no way to fix this as the press produces washers, leading to a large variation in the finished part.

Materials available in many other countries are not as consistent as the domestic steels we use, which gives the imports a cheaper cost, but can lead to failures and inconsistencies when the products are used. The Defense Federal Acquisition Regulation Supplement (DFARS) was created to address this problem. Our materials are DFARS compliant although we do not supply the certification except on special order.
