Flat washer DIN 125A M12 / 13.0 brass

Product detailed description

The DIN 125A M12 brass flat washer is a structural component intended for use in fastening applications where it is necessary to evenly distribute the load under the head of a bolt or nut. This type of washer is made of brass, which is an alloy of copper and zinc, known for its corrosion resistance and good electrical conductivity. Brass is also a material that provides an aesthetically pleasing appearance, which can be an advantage in applications where the visual aspect is important.

The washer is designed according to the DIN 125A standard, which defines dimensions and tolerances for flat washers without chamfer. This standard is equivalent to ISO 7089 and ČSN 021702, which guarantees international compatibility and standardization. The specific dimensions of this washer are: the inner diameter d1 is 13 mm, the outer diameter d2 is 24 mm and the thickness s is 2.5 mm. These dimensions are optimized for use with M12 threads, which is a metric thread with a diameter of 12 mm.

The washer has no surface treatment, which means that it retains the natural properties of brass. This is suitable for applications where additional surface protection is not required or where a surface treatment could affect electrical conductivity.

The use of this washer is wide, from electrical equipment where good conductivity is required, to decorative applications where appearance is important. It is suitable for use in environments with low to medium mechanical stress, where its corrosion resistance contributes to a long service life of the joint.
