Extra Thick Fender Washers | Standard to Extra Large Industrial Sizes

Fender Washers (also commonly known as Mudguard Washers or Penny Washers) feature a much larger outside diameter (OD) relative to their hole size. Their main job is to increase the load-bearing area, making them perfect for securing automotive fenders, plastic parts, and thin sheet metal. By distributing pressure over a wider surface, they prevent the bolt head from crushing or tearing through the material.

At T&Y Hardware, we supply a full range of fender washers in both Metric and Imperial sizes. Beyond standard stock, we specialize in customizing extra-large diameters and extra-thick heavy-duty series to fit your specific needs. Whether for standard industrial use or unique custom projects, we deliver consistent quality with precise tolerances on every order.

Available Materials for Fender Washers

We supply fender washers in a wide range of materials to meet different project needs. This includes our most popular Stainless Steel (SS 304/316) for corrosion resistance, and high-strength Carbon Steel for a cost-effective solution.

For JDM and decorative applications, we also provide decorative or lightweight options like copper (Brass, Bronze), Aluminum, and Titanium, as well as non-metallic materials such as Nylon plastic and Neoprene Rubber.

Fender Washer Styles & Profiles

Along with standard flat fender washers, we also manufacture countersunk fender washers. These are made with a recessed center to hold flat-head screws, allowing the bolt head to sit level with the washer surface. This creates a flush finish that looks cleaner and prevents the screw head from catching or scratching other parts.
