Specific lengths can be produced on request.
See our packaging and palletisation options.
Available finishes
Two finish options to suit your needs:
Plain finish
Blue-white zinc-plated finish CR3 (on request)
HTC (High Corrosion Resistance CR3) zinc-plated finish
- Electrolytic galvanising with a thickness of 8–12 microns
- Intended use: dry indoor environments
- Enhanced zinc plated finish to ensure greater corrosion resistance, suitable for use in damp indoor environments (cellars, sheds, etc.)
Warning: precautions must be taken when carrying out electrolysis treatment or acid cleaning on Class 10.9 fasteners, as there is a risk of fracture due to hydrogen embrittlement. In such cases, a ‘degassing’ process must be carried out. This degassing process cannot guarantee the complete elimination of the risk of hydrogen embrittlement. (See the norm ISO 4042)
