Understanding Fender Washer Sizes — A Complete Breakdown

Choosing the right size of Fender Washers is essential to ensure proper load distribution and fastening stability. These washers are defined by three dimensions: inner diameter (ID), outer diameter (OD), and thickness. The inner diameter must match the bolt or screw size, while the outer diameter should be selected based on the amount of surface area you want to reinforce. Larger outer diameters provide better support, especially when dealing with softer or thin materials.

The thickness of Fender Washers determines how well they handle heavy loads. Thicker washers resist bending under pressure, making them ideal for automotive, machinery, and structural applications. On the other hand, thinner washers are suitable for lightweight fastening where precision and appearance matter more than heavy load-bearing. With sizes ranging from small 1-inch OD washers to larger industrial varieties, Fender Washers offer unmatched versatility across applications.
