Yes they will. I used them on my fence to screw 2" X 10" X 7' pressure treaded lumber on 1" PTR.

can i use to screw a metal piece on top of wood?

the wood im using cannot be moved and i cannot get under it to drill so can i use these and go through the metal first? if not what can i use to go through metal first?
Asked by: sierra7
No, the threads on the screws are not meant to grip into the wood. They are designed to create the matching threads into the metal for the holding power by sandwiching the wood between the screw head and the steel underneath it.

#12 2-3/4 in. Phillips Flat-Head Self-Drilling Screws (40-Pack) is rated 4.4 out of 5 by 18.
Rated 5 out of 5 by from I had read many reviews (here and elsewhere) of these screws, and issues with having to pre-drill... I had read many reviews (here and elsewhere) of these screws, and issues with having to pre-drill holes and using a lot of force to get them through the metal, but I gave them a try anyways. Well after I had installed my first 12 screws (which took forever) I had a sore hand and a dead battery in my cordless driver. So I thought I was going to have to pre-drill like other people had done. While waiting for the cordless to charge, I grabbed my old electric drill with no torque or speed control to give it a try, as I still had 106 screws to go! Well I was amazed! They went in so fast and did not require as much effort as before (still required some pressure downwards). However using this drill I had to be careful not to strip out the heads or over-drive the screws, but it was much easer at higher speeds (which I truly did not expect). Just so you know, the wood was smoking/burning at the speeds I was using. I was going through 1-1/8” thick plywood onto 12 gauge steel along with some 1/8” angles. These are well made and strong steel. I did not break and or strip any out in the end (even on the two screws that brought my electric drill to a complete stop when it cut through the steel). I thought I would write this review to help out others, and let you know faster was better in this case for me. I only wish they had some a little shorter. Good Luck!
