fender washer
A fender washer is a specialized type of flat washer characterized by its distinctively large outer diameter in proportion to its inner hole. This unique design feature provides superior load distribution across a broader surface area compared to standard washers. Typically constructed from durable materials such as stainless steel, carbon steel, or zinc-plated steel, fender washers offer exceptional resistance to corrosion and wear. The washer's oversized outer diameter, usually three to four times larger than its inner hole, makes it particularly effective in applications requiring enhanced surface pressure distribution. These washers are engineered to prevent damage to soft or brittle materials by spreading the clamping force of bolts and nuts over a wider area. Their design also helps in reducing the risk of material failure or deformation in high-stress applications. Fender washers are commonly available in various sizes, with outer diameters ranging from 1/2 inch to several inches, while maintaining relatively small inner hole dimensions. This versatility in sizing makes them suitable for numerous industrial and construction applications, particularly in situations where standard washers might prove inadequate for load distribution requirements.
