These 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. The bolts are therefore suitable for both interior and exterior use, and can be exposed to weather conditions without the risk of rusting. They 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 (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 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.
This guide is for anyone using Forgefix M6 x 20mm roofing bolts. These bolts offer a secure and durable fastening solution for various roofing applications. Note that these bolts are zinc-plated for corrosion resistance, but may not be suitable for all extreme environments.

FAQs
What is the purpose of the zinc plating?
The zinc plating provides a protective layer against corrosion, increasing the bolt's lifespan and maintaining its structural integrity, particularly in outdoor environments.
What tools are needed for installation?
You'll need a drill, appropriately sized drill bit, and a screwdriver or the correct tool to tighten the bolts. A level may also be helpful to ensure proper alignment.
Can these bolts be used with any type of roofing material?
While these bolts are suitable for many roofing applications, always confirm compatibility with the specific roofing material being used. Check with the material manufacturer.
How do I know what size drill bit to use?
The drill bit size should be slightly smaller than the bolt's diameter to allow the bolt threads to grip securely. Refer to the bolt's specifications or consult a hardware professional for guidance.
What should I do if a bolt breaks?
Carefully remove the broken bolt using appropriate tools, such as pliers or a screw extractor. Replace it with a new bolt of the same size and type.
How often should I inspect the bolts?
It is recommended to inspect the bolts at least twice a year, or more frequently in areas with harsh weather conditions. Look for signs of corrosion or loosening.
Troubleshooting
Bolt won't tighten properly.
Check the pilot hole size; it may be too small. Ensure the threads are not damaged and that the bolt is aligned correctly. If necessary, replace the bolt.
Bolt shows signs of corrosion.
Replace the corroded bolt with a new one. Consider using a sealant or protective coating to prevent future corrosion, especially in areas exposed to the elements.
