HI-LOW THREADING
Appropriate for direct fastening on compact and semi-solid materials: natural stone, concrete, solid bricks and hollow bricks.
WOOD FRAMES
Thanks to the cylindrical head, it is ideal for fastening wood frames directly to brickwork supports.
DOOR AND WINDOW FASTENINGS
The hi-low thread allows for safe fastening even near the edges of the support, thanks to the reduced tension induced on the material, ideal for frames.
FAST INSTALLATION
Once the support has been drilled (with a reduced drilling dimension), the screw finds its place directly in the frame, ensuring that the required distance from the brickwork is maintained.
