    Lot of 20 - 069-3322 – 34WWSP - Hardware, Extra Thick Fender Washers 430 Stainless Steel. For 5/16" Bolts. A fender washer is a flat washer with a larger outer diameter in proportion to its center hole. They are designed to spread the load on thin sheet metal. Interestingly, they are named after their use on automobile fenders. Extra Thick Fend Washer 0.120” Thick Dimensions: 2" OD x 0.343” (11/32) ID Material: 430 Stainless Steel Hardware, Extra Thick Fender Washers 430 Stainless Steel. For 5/16" Bolts. A fender washer is a flat washer with a larger outer diameter in proportion to its center hole. They are designed to spread the load on thin sheet metal. Interestingly, they are named after their use on automobile fenders. Extra Thick Fend Washer 0.120” Thick Dimensions: 2" OD x 0.343” (11/32) ID Material: 430 Stainless Steel Package of 20 • Fender washers offer a bolt or screw a wider bearing surface that will disperse the load weight to a greater surface area and ensure that the nut or bolt is pressed up against a smooth surface reducing the chances the fastener loosening over time because of contact with an uneven surface as well as keeping a fastener from pulling through a hole that is larger than the diameter of the head. • A fender washer though similar in shape to a standard washer the outside diameter is much larger in proportion to the center hole. • Made of stainless steel offers a high level of chemical and corrosion resistance and strength that will outperform and outlast zinc plated fasteners for years without the need to perform costly and time consuming maintenance. • The vast majority of stainless steel fasteners are produced with metals from the austenitic family. Their high levels of chromium and nickel provide tough corrosion resistance and the ability to withstand considerable physical strain without fracturing, albeit at a higher cost than the martensitic varieties. • These Fender Washers are made of Grade 430 Stainless Steel which is Magnetic (Does not contain Nickel) and will outlast washers made of steel or zinc for years to come.
