Carbon Steel Self-Drilling Screws 5.5 x 75mm 100 Pack is rated 4.6 out of 5 by 10.
Rated 4 out of 5 by from Tight grip proble, solver I had put batons up above windows using hammer fixings through pre drilled 8mm holes when suddenly one window had metal lintel an inch deep from surface which needed a different approach! Used a 5mm metal drill to go through lintel and used these screws as a long self tapping fix. Didn’t use the self drilling function (as 8mm surface hole too big) Worked really well and gave a good tight grip -only gripe was I could have done with a smaller pack size

Rated 4 out of 5 by from TOUGH SCREWS Bought to attached wood battens to aluminium conservatory sides to form frame work for suspended cladding ceiling. Vert tough self drilling screws, ideal time savers, no pilot holes needed would use again.

Rated 4 out of 5 by from Good product These screws are fine. My only reservation is that I think they will easily corrode and fail after a year or two. Time will tell.

Rated 5 out of 5 by from Better than the average screw Looked through the Screwfix catalogue for a way to fix wood planks to scaffolding. Saw these and did wonder if they would be strong enough as scaffolding is a bit more substantial than was probably indicated in the description. They work a treat, hold tight and not too obvious for the finished result. To be honest, they do work better with a 4mm pilot hole in the scaffolding other wise the screw does spend a while spinning in the wood whilst it drills itself. Great screw fixing.

Rated 4 out of 5 by from Stud Wall Fixings I used these screws to hold brackets to a Stud Wall for fixing a heavy vertical radiator. The screws passed through the plasterboard and into the wooden stud. I could not have been more pleased. Unfortunately 5.5mm washers are not available but I used 6mm washers to spread the load a little.
