Windows Doors Plain
1. Descriptions:
Fast and secure countersunk fixings, suitable for fixing PVCu and
timber frames to masonry, with low expansion force that enables use
close to the edge of frame. As with the majority of concrete frame
screws on the market, these type of screws will not take a normal
screw bit and require the special T30 star-drive.

4. Advantages:
1. No additional plugs are required for screw installation, thus
allowing work to progress quickly and
economically.
2. The small drill bit diameter of 6 mm allows for efficient work,
including in the case of series installation.
3. The continuous thread prevents the window frame from being
pulled against the substrate, and ensures a stress-free and
long-lasting fixing of the frame.
4. The optimised special thread reduces the amount of force
required for screwing in the screws, meaning that the installation
processcan be completed without the use of too much force.
5. Functions:
1. Note the drill hole and screw-in depths for the different
building materials listed in the table.
2. In order to avoid the screw twisting during installation in
concrete, the maximum anchorage depths stipulated must be adhered
to.
3. Cylinder head screws are recommended for recessed installation
in wooden profiles.
4. Flat head screws are recommended for installation in plastic and
aluminium profiles.
