Washer DIN 125 M6(6,4) brass nickel plated

A flat washer is a fastener that looks like a flat disk with a smooth cylindrical hole in the middle, the diameter of which is slightly larger than the diameter of the metric product with which it is used. It is made of steel with a hardness of 140, 200, 300 HV.

DIN 125 is used to increase the clamping area in various types of connections, reduce pressure on the surface of the connecting materials, and reduce friction between the nut and the surface of the part when tightening. In some cases, it is also used as a spacer to increase the distance between the nut and the surface of the part (this may be necessary if the thread of the bolt or screw is damaged at the clamping point).

DIN 125-B items in diameters from 27 to 50 are chamfered washers. The chamfer on the washer facilitates installation and improves interaction with other connection elements, while reducing the likelihood of damage to the material surface when tightening the bolt or nut.

Material of manufacture Brass. Brass washers are used when the system is subjected to frequent dynamic, vibration and cyclic loads. 

Coating Uncoated.
