Rated 5.0 out of 5.0 by Handyfan Work Well, But Need To Be Careful
I've used these on a lot of different small projects and had fairly good luck with them. Here's a couple of things that I've found that help make things go smoother:
1) Always get the hex head product. Even wish the heads were larger.
2) When using these vertically, particularly in a slab, drill deeper than the instructions call for. If not, the installation will get really "tight" or bottom out. If you're not careful you'll round the head and/or your socket.

Used these screws to secure two toilet flanges to the concrete slab, I hate rocking toilets. My house is 20 years old, rust caused the failure of the toilet flanges, Wanted to make sure there would be no rocking. Screws very worked well. The used the 1/4" screw, required a 3/16" hole. The last 1/2" of screwing them in was difficult, required a 1/2" rachet wrench to complete the task.

I wanted to eliminate some sub floor looseness before putting in a new laminate floor by screwing the wooden sub floor to the concrete slab beneath. I predrilled holes the same size as the screw diameter thru the wood sub floor structure, then drilled into the concrete slab using the recommended Tapcon bit and a hammer drill. The holes were drilled abut 1/2" deeper than the screw length, then cleaned muliple times to remove debris. Initially I tried the 3/16" x 3 1/4" screws, but they snapped off while hand tightening. I then bought 1/4" x 3 1/4" , thinking they'd be stronger. Drilled new larger diameter holes following the same process as before. The larger diameter screws snapped before the heads even contacted the wood surface.
A total waste of time and money!
