These Forgefix Phillips Baypole Screws with wafer head are specifically designed for joining PVCu sections, particularly in bay windows. The nails have a self-drill tip and are zinc plated for increased corrosion resistance and durability. The wafer head distributes the load under the screw head, offering a firm positive fixing in a similar way to that of a washer.
The large wafer head distributes the load on numerous types of PVCu sections requiring joining.
Zinc coatings prevent oxidation of the protected metal to create a longer lasting finish. It does this by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not trigger a breakdown of the substrate’s surface integrity as...
