The SPIKE® anchor is a patented, one-piece, tamper-proof vibration resistant anchor for use in concrete, block, brick or stone. Several head styles and anchor materials are available. 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-expanded, there is no secondary tightening operation required which greatly reduces the overall cost of an anchor installation.


  • Pre-Expanded Anchor design allows for easy installation
  • Forming Spike, which is removable can be used for temporary installations
  • Mushroom and flat head spike anchors are tamper-proof
  • Pipe and tie wire spike is an easy to install alternative to direct fastening
