SAE Flat Washers, Grade 8 Plain (USA)

SAE flat washers, also known as Society of Automotive Engineers flat washers, are mechanical components used in various applications. These washers are designed to provide a flat, smooth surface between a nut or bolt head and the surface it is fastened to, such as a metal or wooden substrate. The primary purpose of SAE flat washers is to distribute the load, reduce friction, and prevent damage to the surface or material being fastened.

SAE flat washers are essential components in many mechanical and structural applications, where they help improve the integrity and longevity of connections by reducing stress concentrations and preventing loosening or damage due to vibrations and thermal expansion. They are commonly used in automotive assembly, construction, manufacturing, and various other industries where fasteners are employed.
