Highly ductile (moves with the
wood) and high-resistant steel
(fy,k = 1000 N/mm2)
Asymmetric “umbrella” threading
for better wood penetration
Trivalent Cr3+ ichrome coating,
replacing hexavalent chrome Cr6
FIELDS OF USE
Solid-wood, glulam, X-Lam, LVL,
wood-based panels. Service classes
1 and 2.
The screws’ fast initial grip makes it possible to create secure structural connections in all assembly conditions
The very sharp underhead ribs guarantee an excellent surface finish
STEEL – WOOD
Can also be used with steel plates and hooks, and with turned washers for better performance
Securing X-Lam panels side by side: panel-panel joints

Screws with diameters between 3.0 and 5.0 mm and a length of less than or equal to 50 mm are provided with an unnotched self-perforating tip that increases the grip and hold of the screws. Ideal for using with single bits, it is easily interchanged in the bit holder to obtain the utmost screwing precision.
Screws with diameters greater than 6.0 mm have a notched self-perforating tip that avoids the risk of the wood splitting. Ideal for use with double bits directly attached to the mandrel to obtain maximum screwing force and stability.
