We offer a large catalog of flat washers that are available in materials such as stainless steel, brass, nylon, copper, and bronze.
SAE Flat Washers
We offer the largest selection of SAE Washers in the industry. SAE Washers are also known as Type A Flat Washers, and are named for the Society of Automotive Engineers. SAE Flat Washers are developed to be a smaller, thinner alternative to the standard USS Flat Washers. SAE washers were designed to be used primarily in automotive applications, but can be used across many other industries as well.
