DIN 6921 Flange Bolts

DIN 6921 Flange Bolts have a wide range of applications and important mechanical properties. The head type is a hexagonal flange face. This design provides a larger contact area, which enhances the connection strength and stability between the bolt and the connected parts; the flange face design can provide a larger contact area, thereby increasing friction and preventing loosening. At the same time, the flange face can also be used as a flat gasket to protect the connected parts from damage. DIN 6921 Flange Bolts usually use carbon steel as the main material. Carbon steel has good mechanical properties and machinability and is suitable for a variety of application environments. Through different surface treatment processes, the corrosion resistance of DIN 6921 Flange Bolts can be significantly improved and the service life can be extended. DIN 6921 Flange Bolts are widely used in photovoltaics, machinery, transportation, automobiles, chemicals, heavy industry, construction and other industries due to their excellent performance and wide applicability. In these fields, they play an important role in connection, tightening and support.
