One of the most common forms of Flat Washers are the ‘Type A’ ones.
The Type A Series contains broader tolerances than that of Type B.
Flat Washers are used in conjunction with nuts and bolts. They are designed to sit between the nut and contact surface area which ensures the the pressure is distributed evenly across the washer, therefore reducing damage to the surface area.
