How refreshing to have a screw that you tighten properly using a torx bit.Head of GRK screw is a nice halfway point in size between a more bulky bolt head and a more miniscule Phillips head which may require a washer.

Torx bit that comes with it is cheaply made
Great screws, I'm not a professional, but these things really tighten down. Using them on treated wood to make a deck on my house.
Screws worked awesome. Only problem was there were only 85 screws, 15 short. Can I please get 15 screws sent to me?
Great screw feels like it could hold anything
Know when to stop or you could strip the hole if your driver is strong enough.
Absolutely the best
They really pull wood together fantastically.
Good value
This box of 100 pcs included 1 that was damaged and unusable. Is it possible to receive a replacement?
The best screws for projects that need to last outdoors. They are self drilling and go in like butter
Redoing the deck and these worked great for the old posts. We used to tighten them up.
Works very well. Just what I wanted!
These seem fine. They definitely won't get through metal on their own, despite what the description says here and on the packaging. Broke three screws before giving up and drilling a pilot hole.
Very strong and did the job well!
Worked great & easy to use!
Love the screw but very expensive. Next time will opt for a simple bolt and washer.
At first glance this is the best engineered and manufactured screw I've ever bought. I used these to tie 2x8s into the perimeter of my patio roof and homes exterior walls as the frame work to screen in my patio. These worked beautifully, I did drill 1/8" pilot holes since I was sinking these near the edges of the boards and wanted to be 100% sure I didn't split the wood. When these screws grabbed a stud in the wall they pulled the 2x8 really tight (like a clamping force) from the little cutting threads on the screw. I will definitely be using this again for all my future projects that require a lag screw.
The advantages and ease of a screw with the benefits and strength of a nail. This is the second deck project I used these as structural fasteners; I will look for these for future projects. Highly recommended.
This screw is a beautiful piece of engineering. It is ideal for wood-to-wood connections or even steel-to-wood connections in all kinds of interior/exterior applications. When I can afford these, there is no better lag.
