ISO 4161 Hexagon Flange Nuts

The ISO 4161 standard is an international standard for threaded connections, which specifically stipulates the size, shape and names of each part of the hexagonal flange nut. In addition, the standard also specifies in detail the test methods and quality control requirements for threaded connections.

As a common fastener, hexagonal flange nut is characterized by having a flange surface fixed on one end of the nut body and a cap fixed on the other end. This design makes the hexagonal flange nut have better sealing and corrosion resistance.
