DIN 433


DIN 433

DIN 433 German Standard defines the characteristics like thickness, outer diameter (OD), inner diameter (ID), internal hole, standard, size, materials, strength class, shape, and possible coatings or strength properties. DIN 433 Washers act as a releasable connection or fastening element for all types of components. Most of DIN 433 Washers are made of steel, stainless steel, brass, aluminium, rust and acid resistant materials, heat resistant alloys, alloy steel, unalloyed steel or special alloys with different quality and strengths. DIN 433 Washers are available in all possible sizes for mainly used in Mechanical Engineering, Automotive and Steel Construction.

The following are the features and specifications of
