Answer This Question

A:  Deckmate #9 x 2-1/2 in. Star flat-head deck screws

by|Apr 15, 2020

    A:  i dont know if there is a guide for this but the 2 1/2 inch screw works well.

    by|Jan 27, 2020

    A:  I would always want twice the length as your board is thick. A 5/4 deck board is an inch thick, so 2" minimum.

    by|Apr 15, 2020

    A:  The Deckmate #9 x 2-1/2 in. star flat-head wood deck screw is a good choice for your 5/4" lumber attached to a 2x6" joist.

        A:  Yes. If the wood is very wet, be careful no to drive it too deep. I've used them (shorter ones) to re-plank my deck. They also come in green I believe.

          Answer This Question

          A:  I'm not gonna count them, but the web site says 435 for the 5lb box. (see pic)

          by|Oct 7, 2019

          A:  Good question, there is no indication of the amount of screws on the 5 lb box. However. the 1 lb box says it has roughly 73 screws, So 73 x 5 = 365. Best guess.

          by|Oct 2, 2019

          A:  309 screws per 5 pound box. Great value for the quality of the screw!

          by|May 3, 2021

            Answer This Question

            A:  I'm not sure what the updated 2018 IRC Code is for deck hardware but I'm sure that from a performance standpoint the polymer coating on the Deckmate screw will outperform any hot dip galvanized fastener for corrosion performance especially on ACQ decking.

            by|Feb 1, 2020

              A:  This is not a hot dipped galvanized screw, the packaging simply states they are star drive coated screws. The box also says the proprietary coating prohibits rust and streaking.

              by|Sep 13, 2019

              A:  Yes

                  by|Nov 12, 2019

                    A:  Deckmate 212DMT5 does not meet ICR Code of hot dipped galvanized or stainless steel finish but the Grip Rite galvanized finish is ACQ Rated for use on pressure treated wood.

                    A:  That screw is not made to be used with a washer but if that’s what you need to do I would use a #9 washer.

                          A:  Yes, you can use this item to attached the plywood to the rafters. You cannot use the screws for any load-bearing applications like holding the rafters or joist hangers together. We also recommend using stainless steel screws anytime there is salt spray and increased moisture levels.

                          A:  Box says Approximately 365 pieces. And no, I did not count them

                          by|Jun 10, 2019

                          A:  I would buy a 25lbs of screws for sure, it will save you a good amount of money. I would say a 5lbs. Box has between 250-300 screws.

                          by|Aug 20, 2019

                            A:  They claim 300+ in a box, but I've never taken the time to count them. I'd estimate you'll need at least 4 5-pound boxes for your project.
