These are the correct screws for my 2x6 decking. Warning - If your bit slips in the screw head, remove the screw and toss it. Once the bit slips, either the bit or the screw is stripped or both. Not worth driving damaged screws, in case you need to remove it later.

I used these to secure some timbers that made up our front stairs, I did snap off one of the bolt heads, but the others were fine. I was cranking on the bolt pretty hard with an extension so it was expected.
