parameter
The DIN6923 flat (smooth) flange nut is an integrated flange fastener without anti-slip teeth. Its core advantages include a flat, undamaged contact surface, aesthetically pleasing assembly, and uniform pressure distribution.


Advantages&Functions of Flat Flange Nuts (DIN6923)
Compared to toothed flange nuts, its smooth base does not bite or indent the workpiece surface, preserving protective and aesthetic structures such as paint coatings, anodized layers, and polished finishes. This effectively prevents rust and corrosion caused by coating damage, offering superior protection.
Additionally, the integrated flange significantly increases the pressure-bearing area, evenly distributing clamping force to prevent deformation or collapse of soft materials like thin plates, aluminum, and plastics. Assembly stability is high, and it eliminates the need for washers, simplifying the process and ensuring a clean, smooth surface free of bite marks.
Application Scenarios of Flat Flange Nuts (DIN6923)
Lacking physical anti-loosening teeth, this nut is suitable for static, non-vibrating applications with stable loads and high requirements for appearance and corrosion resistance. It is widely used in precision instruments, sheet metal cabinets, aluminum components, appliance casings, decorative parts, and lightweight fixed equipment, making it an ideal fastener for aesthetic and precision assemblies.
