Timco Self Drilling Hex Head Roofing Screws with EPDM Washers for Light Section Steel (Silver) - 5.5 x 50mm (100 Pack Box) (L50W16B)
These roofing screws & EPDM washers are perfect for fixing roofing sheet to light section steel since up to 5mm 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 patented multi-layer silver organic plating ensures that these self drilling screws will withstand the challenges of the great outdoors since the corrosion resistant finish has been rigourusly tested to prove that it will survive more than 500 hours of salt spray which would usually accelerate rust.
- These screws have an A1 fire classification which means that they are completely non-combustable.
- Using the EPDM washer with these roofing screws prevents water ingress resulting in longer lasting roofing due to a reduced chance of water damage.
