Flat washer DIN 125A M3 / 3.2 nickel-plated

Product detailed description

The DIN 125A M3 flat washer is a structural component intended for use in fastening applications where it is necessary to distribute the pressure of a bolt or nut over a larger area, thereby reducing the risk of damage to the material surface. This washer is made of steel with a hardness of 100 HV, which guarantees sufficient strength and resistance to deformation under normal mechanical stress. The hardness of 100 HV (Vickers hardness) is a measure of the material's resistance to the intrusion of a hard body, which is important for maintaining the shape of the washer under pressure.

The washer has an outer diameter of 7 mm (d2), an inner diameter of 3.2 mm (d1), which makes it suitable for use with screws with a metric M3 thread. The thickness of the washer is 0.5 mm, which is a standard value for this type of washer, ensuring sufficient stability and support for the fastening material.

The DIN 125A, ISO 7089 and ČSN 021702 standards define the dimensions and tolerances for this type of washer, and this washer meets all the requirements of the above standards. The surface treatment is nickel plating, which provides increased corrosion resistance and improves the aesthetic appearance of the component. Nickel plating is a process in which a thin layer of nickel is applied to the surface of the steel, thereby increasing resistance to oxidation and chemical influences.

This washer is suitable for a wide range of applications in mechanical engineering, construction and other industries where it is necessary to ensure reliable and durable connection of components. Its use is particularly suitable in environments where increased corrosion protection is required and where it is necessary to ensure an aesthetically pleasing appearance of the joints.
