Q:I'd like to use this to build a outdoor table with 2" by 8" by 10' pressure treated wood. Is it good to connect 2 piece of wood since the wood actual thickness is only 1.5" not 2"? If this nail is not a good fit, which one I should choose? Thank you

          Worked great throughout treated 4x4’s. Unlike a deck screw, these powered through, didn’t break or have the heads strip.

          Well worth the money!
          I'll never use regular Phillips head screws again. The quality of this GRK brand fasteners is amazing! No pre-drilling necessary and it never splits wood. Screws never break or bend during installation with an impact driver. Screws don't strip or rust

            Excellent product, pricey but well worth the money
            I've been using this GRK brand for many years already. Never had a problem with any of the products. No pre-drilling necessary and it won't split the wood. I've been using them on both, interior and exterior projects. Pressure treated Decking, indoor framing, door and window installation and many more. Strong hold on every application and won't rust. Drives in easily.and doesn't strip.

                  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.

                    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

                      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.

                        These are the best for any project. Saves time and frustration.
