These Forgefix Cavity Wall Anchors are a specialist plasterboard fixing with Pozi and slotted combination drive insert. They have an all-metal construction for applications which require heat resistance and are Zinc Plated for increased resistance to corrosion. The anchors have anti-rotation teeth, which pierce the base plasterboard skin to ensure firm anchorage. APPLICATION:All metal construction means the anchors are suitable for the heavier duty tasks such as fixing radiators and wall units. 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 aluminum and stainless steels by their oxide layers.Cavity Wall Anchor ZP M4 x 45 Bag 10
