The main functions of the hexagonal flange dome cap nut include the following aspects:

Increase contact surface and force area: One end of the hexagonal flange dome cap nut has a wide flange (i.e. flange surface), which increases the contact area between the nut and the workpiece. According to the principles of mechanics, the larger the force area, the smaller the pressure on the force surface, thereby preventing damage caused by excessive pressure on the flange nut contact surface and playing a role in preventing loosening and slipping.

Improving Tightness and Stability: The use of flange nuts can distribute the pressure of the nuts onto the fixed components, thereby reducing the possibility of component damage. Its structure makes the connection between the nut and bolt more stable, able to resist vibration and external force impact, and reduce the risk of loosening.

Excellent anti loosening performance: The tooth shaped structure (such as serrated flange surface) that may be designed on the flange surface enhances the anti loosening effect of the flange nut, providing a certain anti vibration effect. This ensures that the connector does not loosen during movement and high vibration, increasing its security and firmness.

Widely used in various fields: Hexagonal flange dome cap nuts are mostly used for pipeline connections or workpieces that require an increased nut contact surface due to their excellent characteristics and design. For example, it is widely used in industries such as petrochemicals, mechanical equipment, and building structures.

Special function: According to different materials and surface treatments, hexagonal flange dome cap nuts can also have different characteristics. For example, flange nuts made of stainless steel material have good corrosion resistance and are suitable for humid or corrosive environments; And surface galvanizing treatment can improve its rust prevention performance
