Rated 4 out of 5 by from exellent self drilling used these instead of pop rivets,as they were stronger and much quicker. drilling ability is very good on mild steel up to 5mm thick, over that and it's best to pilot drill the hole first with a good hss drill. i was fixing 0.9 mm galv sheets to heavy metalwork up to 12mm thick. first class job!
