DIN 6923 Hexagon Flange Nuts

DIN 6923 hexagonal flange face nut, also known as hexagonal welding nut, is a specially designed fastener. DIN 6923 hexagonal flange nut has a hexagonal shape and one or more flanges. The diameter of the flange is usually larger than that of the nut. There are also some raised teeth on the flange. These teeth are designed to increase the friction between the nut and the parts, thereby enhancing the stability of the connection. DIN 6923 hexagonal flange nuts are divided into different strength levels, which represent the tensile strength and yield strength of the nut and are suitable for different application scenarios.

FAQ

1.What are the technical characteristics of DIN 6923 hexagonal flange nut?

Anti-loosening flange hexagonal nuts designed based on DIN 6923 standard, such as RIPP flange locking nuts with anti-skid teeth, can prevent the nut connection pair from loosening in a vibrating environment. This kind of nut adds anti-skid teeth on the bottom of the flange pad, and relies on the friction generated to achieve the locking effect.

2. Processing and heat treatment?

DIN 6923 hexagonal flange nuts are formed using self-tapping screws and undergo high temperature heat treatment. This treatment can ensure that the surface of the nut is passivated and flat, making it easier to tighten the handle, while avoiding damage to the inner wall of the steel pipe caused by mechanical polywelding and reducing installation time.
