- The surface hardening prevents cracking of the nails as their core remains flexible.
- Nail diameter gradation from Ø 3.0 to 2.6 mm and a ballistic shape of the tip make it easier to drive the nails into hard materials such as steel or concrete
- The grooved surface of the nails increases adhesion to the substrate (load capacity).
- Hardness: 53-56 HRc
- Compliant with PN-84/M-81000 standard
- Galvanized
