Rated 5.0 out of 5.0 by Huskee These GRK screws ROCK
As the others have said, these things are great. Large threads, heavy duty, self drilling, easy to screw in. I too was leery of the star drive but it works flawlessly. After my deck project with these, as well as other deck board screws with the star drive, I will admit I am no longer a "square drive only" snob. The star drive is mighty fine. These screws are the bomb!

Really tough screw that I would feel comfortable building nearly any wood structure with. They bit into the wood easily and the large flat head kept it from pulling into the wood. I closed in one bay of my barn by anchoring 2x8's into the vertical support beams. These screws worked flawlessly.
I wasn't too keen on the star pattern in the end of the head because it requires you to have a special bit. Even though one is supplied with the box of screws, if that one got worn or lost I would not have another to finish the project with. I will say the star driver worked well and didn't slip at all. Also these screws are rather expensive, but the only other option I found was lag screws. I would recommend these if you can stand the price.

Rated 5.0 out of 5.0 by Paul Excellent structural screws
Drills its own pilot, clearances the top board, doesn't cam-out or strip.
Excellent for framing. Not just deck framing, but other tough joints where nails won't keep things together.

Rated 5.0 out of 5.0 by alangski these screws are tough
Used these instead of lag screws when constructing outdoor propagation benches and an outdoor workbench. Quick and easy to run into pressure treated lumber. Designed to really snug up pieces. Store had these in 12-packs.
