High-Quality DIN 6923 Flange Nuts from China Suppliers | Reliable Factory Production of Precision Fasteners
Product Introduction Introduction
Flange nuts are essential fastening components that can be manufactured from high-quality iron or durable stainless steel, with iron being the most commonly utilized material in standard industrial applications. To meet the specific anti-corrosion and aesthetic requirements of customers, these nuts can undergo various professional electroplating treatments.
• Environmentally friendly options: Colored zinc, nickel, blue zinc, black zinc.
• Standard electroplating options: White zinc, colored zinc, black zinc, white nickel.
Usage Characteristics of Flange Nuts Use
Use a pipe cutter or a dedicated grinding wheel cutting machine to vertically cut the stainless steel pipes according to the required length. Ensure you clean the burrs at the end and round them properly.
The left and right conical flange plates (featuring specialized grooves designed for embedding flange gaskets on both sides) are welded securely to the two pipe ports using tungsten inert gas arc welding (TIG welding).
Double-sided flange sealing gaskets are lined and positioned accurately between the left and right flange pieces.
Clamp the two flanges with clamps, then use fastening screws (hexagon socket bolts) to clamp the flange, or use a fastening handle (where one end of the external thread connects to the internal thread of the handle, and the other end connects to the fixed rivet for a flexible connection).
Integrated Washer Functionality: Flange nuts can function effectively as integrated washers due to their toothed round flange face at one end.
How to Use: Locate the designated installation hole, insert the nut, and slowly rotate it clockwise until tightened. Verify the position is fixed and adjust if needed.
Anti-Loosening Performance: Commonly paired with aluminum profile connection angles and T-bolts, these nuts allow fast frame assembly. The unique rotation performance effectively prevents connection points from loosening during long-term use. Using bolts with flange nuts ensures a large contact area, providing superior fastening and anti-loosening effects compared to standard nuts.
