The Zamac Hammer-Screw® is a unique, one-step drive anchor featuring a Phillips type head and a screw thread for use in concrete, block, brick or stone. With a body formed from corrosion resistant Zamac alloy and a carbon or stainless steel drive screw, this anchor has been developed by Powers as an improvement over standard nailin anchors. Traditionally, Zamac Nailin® anchors have been used for light duty, non-engineered applications and have not been recommended for use overhead. In order to overcome these problems, the new Zamac Hammer-Screw® has been designed to provide a removable anchor with 40% higher tension load capacities when installed in concrete. The Zamac Hammer-Screw® can be used overhead provided it is part of an engineered system designed by an engineer who will take the proper design considerations and safety factors into account.
