Description

The washer, also known as washer or U-disc, not only protects the contact surface of the component from damage caused by the tightening of screws or nuts, but also allows for installation with already damaged nut support surfaces. In addition, the use of a washer distributes the load more evenly over a larger area, resulting in a relief of the material and a longer service life. It is optional to use U-washers, however, if these are used, we recommend that you use 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 wet rooms and outdoors. These bearing discs are ideal for the following areas:
