TBS

Large head screw

SPECIAL STEEL
Highly ductile (moves with the wood) and resistant steel (fy,k = 1000 N/mm2).

SPECIAL THREADING
Asymmetric “umbrella” threading for better wood penetration.

ECO-FRIENDLY
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.

JOINT SEAL
The large head guarantees excellent tensile strength which means the use of additional lateral fastening systems can be avoided.

JOINT CLOSURE
The large head offers tight joint closure. The diameter of the head is optimised based on the length of the thread.

JOINT STABILITY
The large head guarantees excellent penetration resistance and allows for stabilisation of joints subject to variations in the dimensions of the wood.

APPLICATIONS

  • Fastening walls at the corners of the structure in X-Lam with excellent joint closure;
  • Fastening walls at the corners of the frame structure with excellent joint closure;
  • Fastening of plaster fibre panels.
