Deana Pidle –
Love that I can get these in packs of 10 instead of the whole case. Super strong and easy to use. I don’t want to use regular screws ever again.
David Markun –
These screws are a life saver. I can drive them with the impact driver and they cut through timber like butter. Way less time than when we used lags and a nicer finish. These are a little less strong than the GRK, but way better priced and plenty for anything we would be doing.
Richard Jaspers –
We built a gazebo using 10″ square timbers. There isn’t too many 15″ screws out there but these really worked well for it. We put the Conceal Textured Log Caulk over the hole and they are literally invisible.
