6.3x25 mm Self-Drilling Roofing Screws, 60 pcs Hex Head Self Tapping Screws, Hex Head Self-Drilling Roof Screws with Rubber Sealing Washer. with Hex Socket, Zinc Plat.

Used to replace the original roof bolts, good quality and easy to use, even got a drill adapter for screwing the bolts in.

Perfect for the job in hand good quality product and easy to use.

Used these to attach 0.5mm metal cladding to battened wall. These are strong and hold tight. initially i used 4x19.mm tek screws but they did not grip tight enough, so i switched to these ones. They drill straight through the metal and attach easily and tightly. Drill Adaptor included.

Excellent item looks and feels top quality highly recommend

All good just enough for the shed roof shed roof s

Worked well

Great

Tried to stich some roofing sheets with these. They failed to drill into the sheet. Had to drill holes in the roofing sheets using a drill and a metal drill bit, and then use these as plain screws, rather defeating the object of these self drilling screws! Also no hex drill adapter supplied, just the screws.
