About This Product

Deck Mate Black deck screws are designed to provide superior weather protection while coordinating with your decking finish. Engineered using star-drive technology, these screws are twice as durable as a Philips drive and prevent stripping. The black ceramic coating provides superior rust and corrosion resistance with 4 layers of protection - a zinc layer, a chemical adhesion layer, an epoxy coating and a durable protective finish. Recommended for use with treated lumber.

Highlights

  • Star drive head helps transfer torque and prevent cam outs
  • Nibs under head allow screw to countersink better for a smoother finish
  • Type-17 point with flute creates its own pilot hole, limiting the need for pre-drilling
  • Black ceramic coating offers superior corrosion and rust protection
  • Flat head leaves a clean, even finish
  • Includes T-25 driver bit in the box

                  The plywood worked exactly as I intended.

                  Screwed to the max… from quality thread to suck up barrels… nothing works so well as a good Torx Stardrive… so I got decked and got back up to enjoy the view

                  I purchased Deckmate screws to fasten edge composite boards for a porch I am building. I appreciate the color variety Deckmate offers in these decking screws. I had no issues with these screws during installation into composite board to pressure treated. Screws are holding up well to sunny hot days and rain. I would buy these again.

                  I use these screws for fence boards, they are very easy to use, better than nails, they are resistant to corrosion, from now on I will only use that type of screws.
                  by
                  This was a great purchase. I bought these to fix a fence that was tilting. The length was perfect to go through the 2x4 and into the treated wood posts. The box of screws came with a free torx bit inside the box, which was a life saver since I had lost mine.

                    I have been using the DECKMATE brand of deck screws exclusively for many years as I find them more consistent in finish, the socket fitting driver and the variety of colors & lengths… I usually countersink before driving them to reduce splitting but even when I don’t/can’t they don’t cause splits as often as other brands… These #8 X 1 5/8” Tan are my Go To screws for 3/4” thick cedar boards on outdoor benches and chairs… Highly recommend them!!..
