Baypole Self-Drill Screw Phillips Wafer Head ZP 4.
8 x 100mm Box 100 - ForgeFix 100BPS4880ZP, 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.
APPLICATION: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 it is formed.
The zinc oxide, if left intact, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminium and stainless steels by their oxide layers.
The Phillips screw has four simple tapered slots.
It is designed so that a Phillips tip screwdriver can turn a Phillips screw with increasing torque.
When the torque gets too strong for the tip, the screwdriver tip winds itself out of the screw thus preventing over-tightening and or damage to the screw head.
A self-drilling screw is similar to a sheet metal screw, but it has a drill-shaped point to cut through the substrate to eliminate the need for drilling a pilot hole.
Designed for use in soft steel or other metals.
