4.8x19 mm Self-Drilling Roofing Screws, 110 pcs Hex Head Self Tapping Screws, Hex Head Self-Drilling Roof Screws with Rubber Sealing Washer. with Hex Socket, Zinc Plat.

quality fixings ordered from my own chair, cheaper (50%) than ordering from Screwfix. used to secure some polycarbonate roof shotes on my self build patio pergola. Quality product and fixes with hex attachment.. don't forget you'll need a hex head for you driver to use these as its so much easier to fit using one of these

Perfect product and did the job as expected.

Used on some vertical metal cladding, great self drilling fixing. Great value.

Good bit of kit great for Ali and steel saves time riveting if you can allow for the heads

Did the job well.

This is what you need to install your metal roof sheets. A great product that drills its own holes and makes them waterproof.

88 pieces only but who is counting !

when you order this product don't forget to ask for attachments for your drill.if you are drilling into two pieces of metal which joins together it has already got a drill bit attached to the fitting of the screw so you do not need to drill pilot hole it does it in one, action drill. And forget.
