The washer also called washer or U-disc, not only protects the contact surface of the component from damage caused by tightening screws or nuts, but also allows mounting on already damaged nut contact surfaces. In addition, the use of a washer distributes the load more evenly over a larger area, which leads to a relief of the material and a longer service life. It is optional to use U-washers, but if they are used, we recommend using a disc made of the same or at least the same solid material as screw and nut. Thanks to the use of high-quality stainless steel, the washer can be used not only in dry, but also in damp rooms and outdoors. These feed discs are ideal for the following areas: Mechanical engineering Car and motorcycle construction. Fence construction. Furniture construction Electrical engineering Ventilation technology. Balcony construction. and much more. Important: washers must not be used with the following screw connections: When using self-clamping screws. When using countersunk screws.
