DECKFAST® COMPOSITE deck screws are designed to eliminate the unsightly mushrooming that can occur in composite decking with most ordinary screws and even some composite screws, Starborn's TransVerse™ threading has been designed to become an industry standard. With its corrosion-resistant epoxy coating and 5 popular colors to choose from, DECKFAST® Composite is the choice for epoxy coated steel composite deck screws. PRODUCT FEATURES: TRANSVERSE™ THREADING Eliminates "mushroom" effect common to composite decking installed using standard deck screws without pre-drilling by preventing debris from the hole from forming a mound around the screw head. SPECIAL HEAD DESIGN Further prevents "mushroom" effect by trapping and pulling back any residual debris under the head. EPOXY COATED STEEL Epoxy-based polymer resin coating over zinc plate for excellent corrosion resistance. The adhesion of DECKFAST®'s epoxy coating is one of the very best on the market. AUGER POINT For faster, easier entry. STAR RECESS Extra deep T-20 star recess to minimize the "wobble" at screw starting found in other brands. ACQ-RATED Approved for use with ACQ treated lumber.
