4.8 mm x 70 mm Roofing Screws, Hex Head Self-Drilling Roof Screws With Rubber Sealing Washer, Rust Proof, Weather Resistant, Zinc Plated, Coarse Threaded, Cladding Steel Screw for Tin Roof (50 pcs)

Used a lot of these when refitting the roof on a recently acquired field shelter for my horse. Easy to use and seem to be holding the sheets well in place, even when windy.

Good value and quick delivery

Great value

i am sure you could use these for many applications without any problem.

I needed to fix triple wall polycarbonate roofing sheets, no problem with a cordless drill with a hexagon drive bit. The sheets are joined with aluminium extrusions into timber bearers and again the drill tip of the screw did the job all in one hit. I did wonder if I might have needed to open up the hole through the aluminium but the screw went straight through. Rubber washer completes the seal.

Quality product and fit for purpose.

Cut through the sheet metal no problem and get a good hold. I used to fix solar panel brackets to the roof of my campervan. Great fix and no movement even at motorway speeds

Good product. Did the job perfectly of fixing PVC sheets on the shed roof.
