Outer tongue stop washer

DIN432Outer tongue stop washerIt is mainly used to prevent bolts or nuts from loosening during use. Through special structural design and installation methods, it provides reliable stopping effect, ensuring the stability and safety of the connection part.

The shape is circular with a protruding tongue (also known as a protruding ear). The main difference between German standard DIN432 and national standard GB856 is that the German standard has a semi-circular arc like a lid, while the national standard does not. Specifications range from 8-36, supporting customized processing of other specifications.

Material: stainless steel, carbon steel, etc. Stainless steel material has good corrosion resistance and oxidation resistance, suitable for harsh environments; Carbon steel material has relatively low cost

Carbon steel surface treatment includes galvanizing (including yellow zinc, white zinc, etc.), hot-dip galvanizing, nickel plating, blackening, etc.

Locking function: During installation,Outer tongue stop washerThe tongue of the nut will be embedded in the corresponding slot or hole of the nut or connected part, preventing the nut from rotating relative to the connected part, thereby achieving a stopping effect.

Reliable anti loosening: By combining multiple anti loosening principles, it can effectively prevent bolts or nuts from loosening under harsh working conditions such as vibration and impact, ensuring the reliability of the connection.

Reusable: DIN432Outer tongue stop washerWith proper installation and disassembly, it can be reused multiple times, reducing the cost of use.

Strong adaptability: There are multiple materials, sizes, and surface treatment methods to choose from, which can meet the requirements of different industries and working environments.

Application field: Mechanical manufacturing: widely used in the assembly of various mechanical equipment, such as machine tools, engines, reducers, etc., to ensure that the connections between components are firm and reliable. Automotive industry: used for bolt connections in automotive engines, chassis, transmissions, and other parts to prevent bolt loosening due to vibration during vehicle operation. Power engineering: applicable to the installation and maintenance of power equipment, such as generators, transformers, transmission lines, etc., to ensure that the connection parts will not loosen during operation.
