A single nut does not constitute a certified EN 14399 assembly. Do not mix structural assembly components without the verification required by the specification. Use the Structural Bolting section for complete assemblies.
Materials and property classes
| Material | Class / hardness | Configurable range | Supply |
|---|---|---|---|
| Steel to mechanical specification | 10 | M12–M30 | On request |
Other materials and specifications on request
For requirements beyond the tabulated combinations, enquire about aluminium, brass, nylon, duplex, superduplex or an ASTM specification. Alloy or grade, dimensions, mechanical requirements and finish are defined for the enquiry; the geometric reference does not automatically imply conformity with the product standard.
Enquire about another material or ASTM specification
Finishes and treatments
| Finish | Material | Class / hardness | M |
|---|---|---|---|
| Black oxide | Steel to mechanical specification | 10 | M12–M30 |
Select the finish for the material/property-class combination. Hydrogen relief and lubrication are separate process requirements, not certificates and not implied by the coating name.
