Highly ductile (moves with the wood) and resistant steel (fy,k = 1000 N/mm2).
Asymmetric “umbrella” threading for better wood penetration.
Trivalent Cr3+ chrome coating, replacing hexavalent chrome Cr6.
FIELDS OF USE
Solid-wood, glulam, X-Lam, LVL, wood-based panels. Service classes 1 and 2.
The large head guarantees excellent tensile strength which means the use of additional lateral fastening systems can be avoided.
The large head offers tight joint closure. The diameter of the head is optimised based on the length of the thread.
The large head guarantees excellent penetration resistance and allows for stabilisation of joints subject to variations in the dimensions of the wood.
