          Extremely Upset

            Southern Sweeps
            Southern Sweeps uses these screws to fasten the firebox to the stud wall when installing the fireplace. looks the fireplace in secure.

              The absolute best screw for structural framing. The self starter tip will eat into pine easy and the star bit imprint is deep so that the star bit will not strip it out. Great for impact guns. Nearly a 1000 lb sheer force with the screw. You can’t go wrong if you build it strong. Get these to do it right.

              I got Significantly less than I paid for
              I got this online and the package was open and less than half full.

                Not sure why everyone loves them.
                Using these for screwing down Advantech subfloor and these screws are NOT self starting. Almost all of them gave me a very hard time starting. I think it may be an issue with the batch because the picture of where the self starting part is does not match the screws I have. The self starting slot is too high on the screws I have so they just don't
                by
                  NOT suitable for exterior. Mine are all rusting.
                  25 months ago, in NY, I constructed in PT lumber some outdoor stairs. Removing stairs now and here are the first 14 (not cherry-picked) screws. This is 25 months. 1/14 shows no sign of corrosion. 13/14 showing corrosion, one with severe (threads already starting to "melt"). Note I used GRK from two batches; it was not a bad lot. Hugely disappointed. Will continue using the screws I have only for interior shelving, basement framing, etc. Absolutely not up to the task outdoors.

                    A no brainer
                    These are the best for any project. Saves time and frustration.

                    Work as advertised!
                    I used the included drill bit and have fastened about 160 of these babies into wood fence posts. Not one screw has stripped, and the self-tap works well. Very pleased with the quality.

                    Excellent, used to attach furring strips
                    We used these to go through the furring strips and then the exterior insulation and the OSB and then into a stud. they have great grab and are strong.
