The Zamac Hammer-Screw® is a unique, one-step nail drive anchor featuring a phillips type head and a screw thread for use in concrete, block, brick or stone. It is available in 1/4 in diameter and lengths ranging from 3/4 in to 3 in. With a body formed from corrosion resistant Zamac alloy and a zinc plated carbon steel or Perma-SealTM coated drive screw, this anchor has been developed as an improvement over standard nailing anchors. The Zamac Hammer-Screw® has been designed to provide a removable anchor with higher tension load capacities compared with traditional nailing when installed in concrete. The anchor is not recommended for overhead, life-safety or sustained tensile loading applications unless special considerations are given to the allowable loads.
