Simpson Strong-Tie Titen Turbo 3/16 In. x 1-1/4 In. Hex Head Blue Masonry and Concrete Screw (100 Ct.)-

The Titen Turbo screw anchor features an innovative Torque Reduction Channel to trap drilling dust where it cant obstruct thread action, significantly reducing binding, stripping, and snapping without compromising strength. The patented reverse thread design enables smooth driving with less torque while providing superior holding power. The Torque Reduction Channel also allows more space for dust to help prevent anchors from bottoming out in smaller-diameter screw holes. The Titen Turbo screw anchors feature a serrated leading edge to cut into concrete or masonry, and a pointed tip for fast, easy installation in wood-to-concrete and wood-to-wood anchoring applications.
