USS Flat Washers, Grade 8 Zinc (USA)

USS flat washers, often referred to as Unified Thread Standard flat washers, are mechanical components used in a wide range of applications, including construction, manufacturing, and various industries. 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. USS flat washers play a crucial role in distributing the load, reducing friction, and preventing damage to the surface or material being fastened.

USS flat washers are essential components in mechanical and structural applications where they help enhance 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 construction, manufacturing, and various industries where fasteners are employed, ensuring that fastened joints remain secure and stable.
