Product Description
Metric A2 Stainless Steel Non-Serrated Flange Nuts – DIN 6923
These metric DIN 6923 flange nuts are manufactured from A2 stainless steel and feature a smooth, non-serrated bearing face. The integral flange spreads clamping load over a wider area than a standard hexagon nut and can replace a separate flat washer where the joint design permits.
Available in M4, M5, M6, M8, M10 and M12, each size has a standard metric coarse thread for use with matching bolts, set screws, studs and threaded bar.

Key Features
- A2 stainless steel construction for corrosion resistance.
- Integral flange provides a broad bearing surface.
- Smooth underside for applications requiring a non-serrated contact face.
- Hexagon profile for tightening with a spanner or socket.
- Standard metric coarse threads across six sizes.
Typical Applications
Suitable for machinery, brackets, frames, equipment assembly and general maintenance where a stainless steel flange nut with a smooth bearing face is specified.
Installation
Use with a bolt or stud of matching thread diameter and pitch. Ensure the flange is fully supported by the mating surface and tighten to the assembly specification. These nuts have no prevailing-torque locking feature; use an appropriate locking method where required by the joint design.
Ordering
Select the required thread size and pack quantity from the available options. Listed M sizes refer to the internal thread diameter.
