characteristic
 
-High strength: usually made of high-strength materials such as stainless steel, chrome vanadium steel, etc., with high tensile strength, compressive strength, and impact strength.
 
-Good wear resistance: Its surface is usually specially treated to improve the wear resistance of friction with the flange surface during the connection process.
 
-Good sealing performance: Different types of flange nuts have different sealing properties, which can effectively prevent fluid or gas leakage.
 
-Easy installation: Using threaded connection method, it can be quickly and accurately installed on the flange.
 
application area 
 
-Mechanical equipment: the connection of components such as engines, transmission systems, hydraulic systems, etc. of transportation vehicles such as automobiles, ships, and airplanes.
 
-Pipeline connection: widely used for pipeline connection in industries such as petroleum, chemical, and natural gas.
 
-In the field of architecture, it is used for structural connections in buildings such as steel structures and concrete structures.
 
-Power industry: connection of equipment such as thermal power plants, hydropower stations, etc.
 
Specifications
 
The common specifications of flange nuts are generally below M20, and some flange nuts above M20 are mostly flat flanges, that is, there are no teeth on the flange surface. These nuts are mostly used for some special equipment and special places.
