It is available in 1/4'' diameter and lengths ranging from 3/4'' to 3''. With a body formed from corrosion resistant Zamac alloy and a zinc plated carbon steel drive screw, this anchor has been developed as an improvement over standard nailin anchors. The Zamac Hammer-Screw has been designed to provide a removable anchor with higher tension load capacities compared with traditional nailin when installed in concrete. The anchor is not recommended for overhead, life-safety or sustained tensile loading applications (see performance data section).
