Fastening group of GOST 13464-77
Washers of GOST 13464-77 are most often made of stainless steel and belong to the stainless fastener group.
Materials for the manufacture of GOST 13464-77 washers
Washers of GOST 13464-77 are made of the following materials:
- Steel, which can be additionally coated with white and hot-dip zinc. It protects the DIN 93 washer from corrosion if the fastener is to be used in aggressive environments.
- Stainless steel grades A2 and A4, this material does not require any coating.
Application range of washers according to GOST 13464-77
The lock washer with a foot is used to prevent self loosening of a threaded connection. The use of this type of washers is necessary when the threaded connection needs to be provided with additional reliability in terms of perception of vibration or other loads, and to eliminate the effects of vibration loads and deformation external resistances that can cause loosening or loosening of the connections. Lock washers of GOST 13464-77 are widely used in those areas of human activity that require meeting the most stringent requirements for fixing system elements and parts: instrumentation, automotive, mechanical engineering, machine tool, construction, and even aerospace.
