Product Introduction Introduction
The basic knowledge of flange nuts is introduced as follows: flange nuts can be made of iron or stainless steel. But iron is more commonly used. And it can also be electroplated according to the color requirements of the customer. There are generally environmentally friendly and non environmentally friendly electroplating treatments.
Electroplating includes environmentally friendly colored zinc, environmentally friendly nickel, environmentally friendly blue zinc, environmentally friendly black zinc, as well as ordinary electroplating such as white zinc, colored zinc, black zinc, white nickel, etc.
Usage Characteristics of Flange Nuts Use
- 1 Tubing: Use a pipe cutter or grinding wheel cutting machine (the cutting blade should be dedicated) to vertically cut stainless steel pipes according to the required length, clean the burrs at the end, and round them.
- 2 Welding: The left and right conical flange plates (with grooves, specifically designed for embedding flange gaskets on both sides) are welded to the two pipe ports that need to be connected using tungsten inert gas arc welding (TIG welding).
- 3 Gaskets: Double sided flange sealing gaskets are lined between the left and right flange pieces.
- 4 Tightening: Clamp the two flanges with clamps, and then use fastening screws (hexagon socket bolts) to clamp the flange or fastening handle (one end of the external thread is connected to the internal thread of the handle, and the other end is connected to the fixed rivet for flexible connection).
Flange nuts can be used as an integrated washer because there is a toothed round flange face at one end, so how to use flange nuts? Let's take a look: When using a flange nut, first find the hole where the nut can be installed, then insert it into the hole location, and then slowly rotate clockwise until tightened. Of course, after tightening, you can check if the position is fixed, and if not, you can adjust it again.
Flange nuts are usually used in conjunction with aluminum profile connection angles. Combined with T-bolts, the frame structure can be quickly assembled, and the flange nut has a certain rotation performance, which can effectively avoid the loosening of the connection point in the later use process. The bolt should be used with the flange nut, and the bolt should be used with the flange nut to make the flange nut fasten with a large contact area, which is easier to use than other nuts and has a better anti-loosening effect.

Frequently Asked Questions FAQ
What materials are flange nuts made of?
Flange nuts are typically manufactured from iron or stainless steel, with iron being the most commonly utilized material in standard industrial applications.
What surface treatments are available for flange nuts?
They can be electroplated to meet specific requirements. Options include environmentally friendly treatments (colored zinc, nickel, blue zinc, black zinc) and standard electroplating (white zinc, colored zinc, black zinc, white nickel).
How does a flange nut function as an integrated washer?
A flange nut features a wide, toothed circular flange at one end. This design distributes the clamping pressure over a larger surface area and acts as a built-in washer to prevent loosening.
How do you install a flange nut correctly?
To install, locate the correct assembly hole, insert the nut, and slowly rotate it clockwise until it is fully tightened. Verify the final position is securely fixed and adjust if necessary.
Why are flange nuts used with aluminum profiles?
When paired with T-bolts, flange nuts facilitate quick assembly of aluminum profile frames. Their rotational slip-resistance prevents connection points from loosening during long-term use.
