The main task of all locking fasteners is to prevent loosening of the threaded connection under the influence of vibrations, high loads and other factors arising during operation. DIN 432 is a standard that defines the characteristics and dimensions of lock washers with an external protrusion. These washers are used to provide additional fixation of nuts and other elements in systems where vibration or movement is possible.
DIN 432 fastening group
DIN 432 washers are most often made of stainless steel and belong to the stainless fastener group.
Materials for the manufacture of DIN 432 washers
DIN 432 washers are made of the following materials:
- Steel, which is additionally coated with zinc. Zinc (Plated) protects against corrosion if the fastener is to be used in aggressive environments.
- Stainless steel grades A2 and A4. Steel grades A2 and A4 allow the fasteners to be used at significant temperature fluctuations and in aggressive and humid environments.
Application range of DIN 432 washers
The DIN 432 washer has the shape of a ring with a protrusion on one side and a flat surface on the other. The protrusion provides additional fixation of the washer and holds the nut in place to prevent it from loosening during movement. These washers are usually made of steel or stainless steel.
DIN 432 washers are used in a variety of industries, including mechanical engineering, automotive, aerospace, and others. They can be used in systems with high requirements for strength and resistance to vibrations and impact.
