Spike® Pre-Expanded Anchor, 8.2 Carbon Steel, Mushroom Head, 1/4" X 3" The Spike® Anchor is a patented, one-piece, tamper-proof vibration resistant anchor for use in concrete, block, brick or Stone.

Since the anchor is pre-expanded, there is no secondary tightening operation required which greatly reduces the overall cost of an anchor installation.
