Self tappers
Works well, the finer thread for thicker metals that won't get stuck and snap off. Just should of bought the longer ones

Best screw ever for heavy iron
I'm a Vine reviewer, but this review is for self drilling screws that I purchased as a customer. I have been involved in steel building construction for a very long time. I'm currently repairing hurricane damage to a warehouse I own in Louisiana. I needed some screws that would drill through 3/8 galvanized steel beam flanges into 1/8" thick purlin steel. I took a chance on these. They are the best I have used or seen used. We have had no break offs. We did burn a couple tips and had to dump those screws, but that is very common when screwing directly through heavy 3/8" steel. We have no issues with these. I rate these the best I have used in 25 years.
