DIN 431


DIN 431

DIN 431 German Standard defines the characteristics like shape, drive style, torque, thread type, standard, size, tolerance, materials, strength class and possible coatings or strength properties. DIN 431 Nuts act as a releasable connection or fastening element for all types of components. Most of DIN 431 Nuts 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 431 Nuts are available in all possible sizes for mainly used in Mechanical Engineering, Automotive and Steel Construction.
