Timco Self Drilling Hex Head Roofing Screws for Light Section Steel (Silver) - 4.2 x 19mm (1000 Pack Box) (00834HWSD)
These roofing screws are perfect for fixing roofing sheets to light section steel since up to 3mm deep they don't require a pre-drilled hole.
- The self drilling point of these roofing screws acts as a pilot drill whilst driving in these screws which significantly reduces the time it takes to install roofing sheets to steel.
- A zinc plating finish means that these roofing screws will begin to rust when exposed to reguarly wet conditions.
- These screws have an A1 fire classification which means that they are completely non-combustable.
