The application and advantages of stainless steel flange hex nuts in practice are reflected in the following aspects:

Enhanced preload: due to the presence of the flange face, the ratio of the support area to the stress area of flange nuts is greater than that of ordinary hexagon head nuts, which makes them capable of withstanding higher preload.
Excellent anti-loosening performance: the design of flange nuts provides better anti-loosening performance, which is especially important to prevent bolts from loosening on their own in vibration environments.
Wide range of applications: stainless steel flange hexagon nuts are widely used in automotive engines, heavy machinery and other fields, these occasions usually require fasteners with high reliability and durability.
Increase the contact area: flange nuts can increase the surface contact area with the workpiece, providing a stronger pulling force compared to the combination of ordinary nuts plus washers.
Suitable for pipeline connections: flange nuts are commonly used in pipeline connections or on workpieces that require an increased contact area of the nut, and their design helps to provide a more even distribution of pressure, thus ensuring the stability of the connection.
CORROSIVE RESISTANCE: Due to the stainless steel material, these nuts have good corrosion resistance and are suitable for use in a wide range of environments, including those where they may come into contact with corrosive substances.
