Most Impressive Screw I've ever used
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.

Great screws
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.

Get a grip!
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.

This screw is a beautiful piece of engineering
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.

Highly recommended.
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.

Know when to stop or you could strip the hole if your driver is strong enough.
