  • Roofing bolts can be used on many DIY projects other than roofing.
  • These double slotted roofing bolts have a low profile mushroom head.
  • Their bright zinc plated finish increases resistance to corrosion.
  • The bolts are therefore suitable for both interior and exterior use, and can be exposed to weather conditions without the risk of rusting.

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 substrates 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.
