DIN 1440 reinforced washer, flat for DIN 1444 steel axle, manufactured in accordance with ISO 8738 and GOST 9649-78 standards.
The distinguishing feature of the DIN 1440 washer is its large inner diameter and thickened mounting height. These parameters are necessary for installing the washer for oversized nuts, bolts and other hardware products.
This DIN 1440 washer is designed to work together with a pin (steel axle), so when choosing a size, note the diameter of the DIN 1444 pin, which must match the inner diameter of the washer.
The material used for the manufacture of DIN 1440 washers is carbon steel, galvanized steel and stainless steel A2-70; A2-80; A4-70; A4-80. The choice of material and its coating depends on the conditions and environment in which the fasteners are used.
The flat washer DIN 1440 is used in threaded joints with high vibration and dynamic loads. These are most often machine tool manufacturing, shipbuilding, and other industries.
