I have a very big container of new Deck Screws. The container says 2000. The color is Desert Sand. The size is #9 x 2 1/2". I have attached many photos. They have a very unique thread pattern to assist proper installation with minimal tear out, designed specifically for composite decking. Look at photos to get name of manufacturer, size and color. I did find the exact same screw online and the price was $189 and $249 for 2000 of these screws, different color. $100 is about 1/2 price. Torx drive, T-20, small heads.
I will only take phone calls from interested people so don't waste your time or mine.
