Invisi-Fast fastners come in five models; four of them are made of clear, paintable polycabonate plastic
Four of the five Invisi-Fast Biscuit models are made of clear, paintable polycarbonate plastic, which is much stiffer than the polyethylene plastic used in some other fasteners.
Each rectangular-shaped fastener is screwed straight down into the joists. The NM model works on a variety of grooved deck boards and registers a 3/16-in. space. The TD model is sized for TigerDeck hardwood decking; the TT model is designed for TimberTech decking; the TQ model works on 3/4-in. deck boards with a 1/8-in. groove; and the TXB model is made of black colored plastic and is designed specifically for Trex grooved deck boards.
