The Simpson Strong-Tie Titen Turbo installation kit makes installation of these concrete and masonry screw anchors quick and easy. Accessories are compatible with standard quick-release or three-jaw style chucks. The sockets have been designed to prevent over-torquing, which can lead to fastener failure. The kit comes with a convenient zipper-close canvas bag for easy storage of installation-kit parts and Titen Turbo screw anchors. Kit includes: 6-lobe bit socket, T25 and T30 bits, 1/4 In. and 5/16 In. hex sockets and canvas storage bag.
