PRODUCT SPECIFICATIONS: An approved fastener (by Trex) for Trex composite decking, these gray carbon steel screws have a T20 6-lobe drive type, have a #10 screw size, and are 2-3/4 inches long with a 0.23 inch diameter cap head.
INVERTED UPPER THREADS: Right below the head on each of these screws is a set of inverted threads, which serve as a means to clear excess material as it drives through, while also ensuring that the screw is seated properly and consistently.
SMART DESIGN: The cap head design on these deck-drive screws inhibits mushrooming and prevents material from rising up above the deck for a smoother, clean-looking installation. Moreover, the 6-lobe drive ensures secure, hassle free-driving.
DAMAGE PREVENTION: The Tri-lobe threads of these deck screws reduces damage to the composite board while driving. In addition, the screws' unique cut points can easily penetrate composite decking material, making for a fast start.
