The Spike® is a one-piece, vibration-resistant anchor for use in concrete block or stone. The Spike® anchor is formed with an "s" shaped configuration at the working end of the anchor to create an expansion mechanism. Since the anchor is pre-formed, there is no secondary tightening operation required which greatly reduces the overall cost of an anchor installation.
