DEWALT Impact Nail & Pin Anchors ZAMAC HS 1/4 X 1 QTY: 100

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" 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).
