Fender Washers
We Offer a Large Selection of Fender Washer Sizes
We offer all types of fender washer sizes to meet your demands. Compared to standard flat washers, fender washers have much larger outside diameters in proportion to the hole size. The large diameter on stainless steel fender washers provides a larger bearing surface for assemblies, and spreads the load over a wider area. Contractors and technicians are able to embed fender washers and spacers under bolts to balance pressure that is created while tightening. In addition, our selection of fender washer sizes are able to be embedded between a steel screw and an aluminum surface to prevent the formation of corrosion.
At Willie Washer, we specialize in manufacturing fender washers to precise specifications. Our advanced in-house capabilities allow us to fabricate washers in a variety of materials, sizes, and finishes to meet the needs of different industries. Whether you require a prototype or a large-scale production run, we have the technology and expertise to ensure consistency and quality.

Industries That Rely on Fender Washers
Fender washers were historically used in the automobile industry, initially being utilized on automobile fenders. Due to their unique design, fender washers of all sizes are an excellent choice for a number of industries where large outside diameters and thin materials are needed.
In addition to automotive applications, fender washers are popular in:
- Heavy equipment manufacturing
- Construction – to distribute load and prevent damage when fastening thin or soft materials
- Infrastructure projects
- Marine applications – stainless steel fender washers resist rust and provide long-lasting reinforcement in high-moisture conditions
The large surface area of fender washers ensures secure fastening while reducing the risk of material damage, making them essential in environments where stability and reinforcement are key concerns.
Customization and Material Options
In addition to standard fender washers, double thick fender washers (1/8”) are also available for heavier application needs. Fender washers are available in various premium finishes, such as zinc & yellow, zinc & clear, black oxide, nickel, phosphate & oil, and many other custom finishes. In addition to offering a large selection of fender washer sizes and finishes, we also offer these parts in materials such as stainless steel and low carbon steel. In addition to fender washers, we offer a large catalog of other components, including belleville washers, cup washers, tab washers, and wave spring washers.
We create washers in an array of materials to accommodate different environmental and structural requirements. Low carbon steel fender washers provide a cost-effective option for general-purpose applications, while stainless steel fender washers offer enhanced corrosion resistance for long-term durability. Additional coatings, such as zinc plating, black oxide, and phosphate finishes, are available to extend product life and improve performance in harsh conditions.
