Locking washer DIN 463 is manufactured in accordance with the national standard GOST 13463-77 for locking hexagonal bolts and nuts.
The DIN 463 washer is widely used in mechanisms and structures that are subject to high vibrations and in important connecting units, where accidental loosening can lead to human and financial losses. These include the production of military and space equipment and aircraft structures.
To install the DIN 463 washer, bend one leg over the edge of the workpiece and bend the other leg over the head of the hexagonal bolt or nut. This reliable fixation protects the structure and the people themselves from serious emergencies.
Carbon steel, zinc-coated steel, stainless steel A2-70; A2-80; A4-70; A4-80, brass are used to manufacture locking washers DIN 463. The choice of material depends on the environment in which the fastener is used.
