Forgefix double slotted roofing bolts are supplied with square nuts and have a low profile mushroo...Forgefix double slotted roofing bolts are supplied with square nuts and have a low profile mushroom head. Their bright zinc plated finish increases resistance to corrosion, making them suitable for both interior and exterior use and exposure to weather conditions without the risk of rusting. These bolts are used in many applications other than roofing, when joining products together. Use clearance drill sizes 1mm larger than bolt diameter. 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 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 aluminium and stainless steels by their oxide layers. With slotted screwdrivers, it is important to ensure that the tip matches the width of the screw slot, otherwise you run the risk of damaging the screw head. Slotted screwdrivers are available with either Flared or Parallel tips. For the majority of uses the Flared tip is ideal, but if the screw/bolt needs to be driven below the material surface, a Parallel tip screwdriver should be used.

FAQs
What is the purpose of the zinc plating?
The zinc plating provides corrosion resistance, extending the lifespan of the bolts and protecting the underlying metal.
What size screwdriver do I need?
You need a slotted screwdriver. Ensure that the tip matches the width of the screw slot.
Can these bolts be used outdoors?
Yes, the zinc plating makes them suitable for both interior and exterior use and exposure to weather conditions.
What materials are these bolts suitable for?
They are suitable for use with materials like wood and some metals.
What if the bolt is too long?
If the bolt is too long, the excess length may not allow for proper tightening. Use the appropriate length for your application.
How do I choose the correct bolt size?
Measure the thickness of the materials being joined and select a bolt length that allows for sufficient thread engagement with the nut.
What is the benefit of the mushroom head?
The mushroom head provides a low profile and helps to distribute the load, offering a secure hold.
Troubleshooting
Bolt head stripping during installation.
Ensure the correct size slotted screwdriver is used. If the screw head is damaged, replace the bolt.
Bolt not tightening properly.
Check the nut and bolt threads for damage. Ensure the bolt length is appropriate for the materials being joined.
