Product Description

Flange nut, also known as washer nut, serrated nut, hexagonal flange nut, etc., has a wide flange at one end and can be used as an integrated washer. The following is a detailed description of the flange nut:

1. Structure and design: Flange nuts are mostly hexagonal in shape and made of hardened steel, usually with a galvanized surface treatment. The flange increases the contact area with the workpiece, which helps to evenly distribute the pressure of the nut over a larger surface area, thereby reducing damage to the components and improving the stability of the connection.

2. Materials and specifications: The materials of flange nuts are diverse, including A3 low carbon steel, 35K high-speed steel wire, 45 steel, etc., with hardness levels ranging from level 4 to level 12. Common specifications include M5, M6, M8, M10, M12, M16, etc. Specifications above M20 are relatively rare and mostly flat flanges (i.e. flanges without teeth).

3. Features and uses: The flange nut has an anti slip tooth pattern design, which can increase friction and prevent the nut from loosening. They are commonly used in applications that require high tightness and stability, such as pipeline connections, fixing metal plates, elevator manufacturing, and marine engineering. The serrated flange of the flange nut can also provide locking function to prevent loosening of fasteners caused by vibration.

4. Advantages: The flange nut can be adjusted and disassembled after installation, making it flexible to use. They reduce the preload force by utilizing the remaining rotational resistance, thereby maintaining a good fastening effect.

In short, flange nuts play an important role in various situations that require high tightening force and stability due to their unique design and superior performance.
