Inner fan washer DIN 6798I M4 / 4.3 galvanized

Product detailed description

The internal fan washer DIN 6798I M4 / 4.3 is a specific type of fastener designed to ensure the reliability and stability of connections. This washer is made of spring steel, which provides it with high resistance to mechanical stress and wear. The surface treatment with galvanic zinc increases its resistance to corrosion, thus extending its service life even in difficult conditions.

The washer has internal teeth, which ensure effective force transmission and prevent spontaneous loosening of the screw connection. This type of washer is suitable for applications where it is necessary to ensure a strong and stable connection, for example in mechanical engineering, the automotive industry or when assembling various mechanical devices.

The size M4 / 4.3 indicates that the washer is designed for screws with a metric thread M4, while the inner diameter of the washer is 4.3 mm. The DIN 6798I and ČSN 021746 standards guarantee that the washer meets all requirements for quality and manufacturing accuracy according to internationally recognized standards. This component belongs to the category of toothed washers, which are known for their ability to increase friction between connecting elements and thus increase the safety of joints.
