Flange nuts, also known as pad nuts, serrated nuts, hexagonal flange nuts, etc., are commonly used for pipeline connections or workpieces that require an increased nut contact surface. The design feature of this nut is that it has a wide flange at one end and anti slip teeth at the bottom. This design not only increases the contact area between the nut and the workpiece, but also simplifies the assembly process through the integrated design of the gasket and nut, avoiding the use of additional gaskets. This design makes the flange nut more secure during connection, suitable for situations that do not require very accurate alignment, especially in vibration environments where it can maintain good connection stability and reduce looseness.
In contrast, ordinary nuts usually do not have flange designs and need to be used in conjunction with washers. Although this design has a wide range of applications, from daily furniture assembly to the connection of lightweight mechanical equipment, ordinary nuts may not be able to meet the requirements in high-strength application fields such as automotive engines and heavy machinery that require high tightening force and long-term stability. In addition, regular nuts may require additional anti loosening measures during installation, such as spring washers or locking nuts, to maintain the firmness of the connection.
In summary, flange nuts have advantages in connection scenarios that require high tightening force and long-term stability due to their integrated design and increased contact area, while ordinary nuts are still an economical and practical choice in many applications that do not require extreme tightening force due to their wide application range and lower cost.
