Thank you for choosing Trex. The regular Hidden Fasteners can not be used with Elevations, you will need to get the Hidden Fastener specially for Elevations or a steel substructure. If you have any further questions, please feel free to contact us Monday through Friday 8am-5pm EST at 1-800-289-8739. Erin, Trex Customer Care
Dear Gary: We also ran into problems with these plastic Trex fasteners. We switched to stainless steel FastenMaster clips, which include 'starter' clips for edge boards. See: FastenMaster Model #FMTHDCLIP-200, Home Depot Internet #312936835, UPC Code #608309444169, Store SKU #1005403573 A tip for 'pro' level decking: 'Picture frame' your deck with two courses of boards that run parallel with the perimeter. This improves the appearance and eliminates the small ends on two sides. You can also install a slightly different (typically darker) color around the perimeter. This does require installing 'ladder blocking' on the sides where the joists are parallel, every 16 inches or more. We also install 'skirt' boards around the sides, on the rim joists -- using FastenMaster Cortex hidden screws and caps. Caps are available for almost all types of decking. Home Depot carries these too. Finally, did you check your deck for safety, before you installed the decking? Every deck I have inspected had at least one serious problem -- often two or more, e.g. joists bolted to the sides of posts, no tension ties to hold the deck to the house, no tension ties on the guardrail posts, etc. etc. Do a Web search for "Top Ten Deck Building Mistakes" from FineHomeBuilding, the "Prescriptive Residential Wood Deck Construction Guide" from the American Wood Council, and "deck tension ties" from Simpson. Note that there are two types of lateral tension ties for the ledger board / house connection, and twice as many are required if you use the easier-to-install version that uses a screw into the rim joist of the house. The version that uses a threaded bolt through to brackets on both sides is significantly stronger. I hope this is helpful, Mark

They should. I used mine on a non-Trex product and they worked fine, but it wasn’t fibercon.
Trex instructions indicate we should use one fastener on each joist. See the below link to download the Trex decking installation instructions. https://documents.trex.com/is/content/Trex/19TRX017_Trex%20Decking%20Install%20Guide_2020pdf.pdf
Trex recommends a 3/16" minimum and 1/2" maximum spacing to allow for expansion and contraction. See the following URL for installation information. https://documents.trex.com/is/content/Trex/19TRX017_Trex%20Decking%20Install%20Guide_2020pdf.pdf
Your math is good, you just need to ensure a tight fit with each board gap. On my deck, I used square-edged board around the perimeter (so the grooves werent showing. Those edge boards had to be rip-cutted on the long edge. It is a little hard to plan a deck size perfectly so a board doesn't have to be ripped, especially if the edge boards are overhanging fascia. A lot needs to be taken into account.
Dear Mike: Yes, although I recommend stainless steel Fiberon hidden deck fasteners, which are easier to install. See: Fiberon Model # BKT BRD VER HF C90, Home Depot nternet #202671704 , UPC Code # 844219008002 'Square edge' decking board does not have a groove for hidden fasteners. If you plan to install square edge around the perimeter of your deck ('picture framing') , the boards need to fastened with small L brackets from the under side of your deck,. On the outer side, these brackets are covered by a composite 'skirt board' that is attached to the rim joist.. Another option is FastenMaster Cortex screws and caps; caps are available to match most types and colors of composite deck board. For example see: FastenMaster Model # SCREW FIB IPE, Home Depot Internet #302200945, UPC Code # 844219012986 If you plan to 'picture frame' your deck with square edge boards, also read up on "ladder blocking", which needs to be installed between the joists on the sides. I hope this is helpful, Mark
I would not recommend these for steel
