Fan washer external DIN 6798A M16 / 17.0 galvanized

Product detailed description

The fan washer with external teeth according to DIN 6798A and ČSN 021745 is a special type of fastening material designed to secure bolted joints against loosening due to vibration or dynamic loading. This washer is made of spring steel, which provides it with the necessary flexibility and resistance to deformation. The surface treatment with galvanic zinc increases its resistance to corrosion, thus extending its service life even in difficult operating conditions.

The washer has external teeth, which during assembly creates additional friction between the joined surfaces, thus increasing the stability of the joint. The teeth dig into the surface of the material when the screw is tightened, thus preventing the joint from loosening spontaneously. This particular washer is designed for bolts with a metric thread M16, and its outer diameter is 17.0 mm.

The fan washer with external teeth is ideal for applications where it is necessary to ensure the reliability and stability of bolted joints, such as mechanical engineering, the automotive industry, construction and other technical areas where the joints are exposed to vibrations or dynamic forces. Its use is particularly suitable where other types of securing elements, such as adhesives or lock nuts, cannot be used.
