Transverse threading on these epoxy coated screws 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. The special head design further prevents a "mushroom" effect by trapping and pulling back any residual debris under the head. Screws also feature an auger point for easier, faster entry.
These steel screws are first given an undercoat of zinc plating over which an epoxy-based polymer resin is applied. The epoxy coating provides excellent corrosion resistance for outdoor applications. Approved for use with ACQ treated lumber.
350 count "Deck Pack" boxes contain screws for 100 square feet of decking, 1,750 count "Pro Packs" contain screws for 500 square feet of decking.
Note: Due to usage variables we cannot guarantee these screws against corrosion. When using acidic woods, such as Redwood or Western Red Cedar, or building in seaside applications 316 stainless steel screws are recommended.
