My problem with tapcons isn't the strength. It's that I've never had great luck getting them to tighten and not strip out
Do you use their drill bit, or your own? I have a set of Bad Dog bits and the smaller TapCons don't work with the 3/16"" bit, but the 1/4" and 5/16" do. I gave up on the small TapCons because my Milwaukee hammer drill twists the heads off every time. If a stud sticking out isn't a problem, I sometimes use wedge anchors (NOT Acme-Johnson).
