No other screw product can perform like Poly3 in the hard, brittle types of wood/poly composite lumber. Period. Of course, Poly3 also works great in original wood/poly formulations too. Multiple patented features make Poly3 the quick and easy one-step installation choice and DuracoatXT will help keep your composite project looking great for a long time.
#1 and #2. Real self drilling with the combination of patented spiral channels (2) and patented Power Point Technology (1) for smooth, even drivability. No predrilling is needed. Save time, minimize labor and increase project longevity with our one-step installation. Compare: Unlike almost all composite screw products, they are removable. You really have to try them to believe it.
#2. Proven DuracoatXT coating far outlasts galvanized and other special coatings. DuracoatXT is also impact resistant and non-staining and won't "peel" while being installed like ceramic coatings can. It is also a low heat coating process that doesn't make the screw weak (hydrogen embrittlement) like some galvanized coatings can. DuracoatXT Test Comparison Wood/Poly Composite-To-Product Reference XT For Under The Deck. What are you fastening your composite decking to? Under the deck, the new generation of ACQ, CA, and CCA treated wood materials demand a much better coated composite fastener than ever before. Poly3, with DuracoatXT, has been engineered expressly for and is the best-by-test solution for these new treatments.
Available in 3 popular DuracoatXT colors to suit your project.
#3. Special V-Roll head resists overdriving and our cutting flutes gives a beautiful flush fitting countersink. No need for extra "finishing" steps, like hammering or sanding, that you must do with some other screw products. V-Roll Head seals the surface against moisture intrusion that can rot supporting beams. No snapped heads. #10 diameter and special design head gives a nice looking flush fitting countersink with no snapped heads. Compare: No snapped heads during construction and no head popping post construction. Today's decks undergo significant post construction stresses as they dry out. Poly3's head strength alleviates this problem. Popular square drive for less chance of drive bit cam-out.	No finishing needed like the screw on the left.
#4. Special coarse threads hold tight even in soft, wet, green or treated supporting substrates.
