Powers Fasteners 03794-PWR 1/4" X 2-3/4" Concrete Forming Spike Anchor 100/Box

Forming Spike - Designed for concrete forming. The published length is measured from below the head to end of the anchor. 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.
