These are awesome screws for big rough cut lumber

Screws are flawless

I was shocked with the cost of shipping, but the 50 screws I ordered were exactly what I needed for my deck rebuild. Shipping was almost as much as the screws themselves. I could understand that for a larger order, but for 50 screws, I felt that was unnecessary. A few dollars would cover the real shipping cost for the small box of screws.

very competent screws

These torx flathead screws appear to be of high quality. I have sunk about 200 so far and
not had a single break or torx strip. Some screws were driven so hard that the geared driver drill required a right-angle brace to keep control of it.
