Designed with an integrated flange beneath the hexagonal body, these nuts provide a larger bearing surface than conventional hex nuts. The flange helps distribute clamping pressure over the connected component and can reduce the need for a separate washer in suitable assemblies.
SENOTECH supplies DIN 6923 flange nuts, hex flange nuts and serrated flange nuts for automotive components, machinery, industrial equipment, steel fabrication and general fastening applications.
DIN 6923 specifies flange nut dimensions for metric coarse and fine threads, with standardized sizes from M5 to M20.
Serrated Flange Nuts
Serrated versions feature teeth on the underside of the flange. These serrations increase resistance against rotation after tightening and are commonly selected for machinery, automotive and equipment assemblies subject to vibration.
For applications where the contact surface must remain smooth, non-serrated flange nuts can also be supplied according to customer requirements.
