DIN 6923
Hexagon nut with smooth flange
An integral flange with a smooth, non-serrated bearing face. It provides a wider bearing area than the hexagonal body.

Variants and dimensional data
The table identifies the reference technical selection. The supply configuration is reviewed against the enquiry.
Dimensions in mm. Identification drawing, not a manufacturing drawing.
| M | Pitch P | s | h max. | dc max. flange |
|---|---|---|---|---|
| 5 | 0.8 | 8 | 5 | 11.8 |
| 6 | 1 | 10 | 6 | 14.2 |
| 8 | 1.25 | 13 | 8 | 17.9 |
| 10 | 1.5 | 15 | 10 | 21.8 |

| 14 | 2 | 21 | 14 | 29.9 |
| 16 | 2 | 24 | 16 | 34.5 |
A smooth flange is not a prevailing-torque feature and is not equivalent to the serrated design. The M10 wrench size in this selection is 15 mm: check differences from EN designs before substitution.
Table dimensions refer to the stated execution. DIN/UNI, polymer and special variants require verification of their own dimensions; they do not automatically inherit reference geometry, weight or performance.
Materials, classes, finishes and treatments
Executions are distinguished by reference, material, class and finish. DIN, ISO and UNI references do not imply dimensional equivalence or availability of every size in each material. Supply and batch documents require quotation confirmation.
| Execution reference | Material | Class / hardness | Documented finishes |
|---|---|---|---|
| DIN 6923 | Stainless A2 | To be specified | To be specified |
| DIN 6923 NS (flangia liscia / smooth flange) | Stainless A2 | To be specified | To be specified |
| DIN 6923 NS (flangia liscia / smooth flange) | Stainless A4 | To be specified | To be specified |
“To be specified” is a requirement not established by this selection; it does not imply class 70/80, HV hardness or an automatic finish. Steel property classes do not apply to nylon/polyamide; PA6 and PA66 are distinguished only where stated. For nuts with non-metallic inserts, the material shown is the body material.
