Powers Fasteners 05530-PWR Description

Mushroom Head Carbon Steel Spike (Tamperproof) - The SPIKE® anchor is a patented, one-piece, tamper-proof vibration resistant anchor for use in concrete, block, brick 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-expanded, there is no secondary tightening operation required which greatly reduces the overall cost of an anchor installation.
