Mushroom Head Grade 8.2 Carbon Steel Spike
The SPIKE® anchor is a patented, one-piece, vibration resistant anchor for use in concrete, block brick or stone. The SPIKE® anchor is formed with an "S" shaped configuartion at the working end of the anchor to create an expansion mechanism. Since the anchor is pre-expanded, there is no secondary tightening operation required wich greatly reduces the overall cost of an anchor installation.
