    Do you need a screw on each floor joist with 12” spaced joists
    ByJun 25, 2026
    1 Answer | 
    Answer This Question

    Thank you for your question. When installing Hidden Fasteners, one fastener is required at each joist. In situations where two boards meet on a single joist, we recommend using the Trex Hideaway Butt Joint Clip to allow for proper spacing and support. Alternatively, you may install a 2 x 4 nailer board at the joist location and secure the boards using two Trex Hideaway Universal Hidden Fasteners. Thank you, Brooke - Trex Customer Care Team

      If I’ve pulled off the old wood decking that was nailed down, and I’m not replacing the joists, are these screws long enough to give me a good hold in the older wooden choice
      ByJun 18, 2026
      1 Answer | 
      Answer This Question

      Thank you for your question. The screws included with the hidden fasteners are designed to provide a secure hold. When reusing wooden joists, we recommend using Trex Protect Joist Tape for added protection and improved performance. If you have additional questions, please reach out to us at 1-800-289-8739 or at customercare@trex.com. Thanks, Brooke - Trex Customer Care Team

          Will these work with Deckorators Summit 1”x 6” composite deck boards?

          1 Answer | 
          Answer This Question

          Hey Scott! 👋 Great question—we recommend checking with Deckorators to confirm that Trex Hideaway fasteners are approved for use with their boards. That’ll ensure the best performance and proper install. 👍Brandi -Trex

            Answer This Question

            For a 168 sq. ft. area, you’ll need roughly 250 fasteners assuming a maximum 16" joist span. It’s always a great idea to have a few extra on hand just in case. Let us know if you need anything else—we’re here to help! 🛠️ Brandi -Trex

                  We used these Trex Universal Hidden Deck Fasteners while installing our composite decking, and they worked great. The clips made it easy to keep consistent spacing between the boards, as recommended, while keeping all of the screws hidden. The finished deck has a much cleaner appearance without visible screw heads. I also liked that the screws are already attached to the fasteners, which made installation quicker and saved us from having to handle a bunch of separate pieces. The included bit worked well and helped prevent the screws from being driven too far. Overall, these are sturdy, easy to use, and made a big difference in the finished appearance of our deck. I would definitely use them again for another composite decking project.

                  I used the Trex Deck Fastener Kit on my deck project and was really impressed with how well it worked. The installation was pretty straightforward, and the fasteners made it easy to keep the boards evenly spaced and secure. The biggest difference is the finished look — not having visible screws across the top of the deck gives it a much cleaner, more professional appearance. The clips and screws felt like good quality, and everything went together without any issues. Overall, I’m very happy with the kit and would definitely recommend it to anyone installing Trex decking. It made the project easier and the final result looks great.

                  Worked perfectly for building our deck. Easy to use and the big bucket provided enough product for our 12x36 platform deck.

                  Install recommends 3/16" gap minimum. Hidden fastener actual gap 1/4". Way too big!
                  Trex installation manual specifies a width to width gap of 3/16, yet their hidden fasteners are 1/4" when measure with a caliper and their manual states "When you use the recommended hidden fasteners, the placement of the hidden fastener establishes the designated gap size." That's not accurate at all. 1/4" is way too big imo. Closest you can get is Deckmate that claims 3/16" but is actually 7/32. It's plastic. Not hard to make the right size. Always making things more difficult than they need to be.

                    Screw broke after minimal torque
                    The screw in the hidden fastener broke after minimal torque - now I need to also remove the old bit from the joist.

                    Hello Vincent, we sincerely apologize for your negative experience. However, we would like to mention that our screws are stainless steel and do not contain carbon which is what makes screws harder. We do not include this in our screws to avoid concerns with rust. This means our screws will be softer and would need to be installed with a regular drill. We would also advise against using an impact driver when installing them and to make sure you lower your torque. If you have any further concerns, please contact our customer care team at 1-800-289-8739 so we can further clarify the situation. - Trex Customer Care Team Trex

                      Buy These fasteners!
                      I bought two other types of universal fasteners from Fiberon for my deck project. They worked...most of them broke very easily causing us to take up boards a few times. The Fiberon ones were ordered online so you can't get them in store. We ended up buying these TREX fasteners and WOW...way thicker, heavier and more durable. Didn't break a single fastener! I wish we had just spent $5 more bucks and got these for the whole deck. Learn from our mistake! Buy these if you are doing grooved composite
