3/16" x 1-1/2" Powers Mushroom Head Spike Impact Anchors 316 Stainless Steel Package 100 - Box
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 and expansion mechanism. Since the anchor is pre-expanded, there is no secondary tightening operation required which greatly reduces the overall coast of an anchor installation.
Once seated at the required embedment, residual spring forces developed in the expansion mechanism provides three compression forces at the bottom of the anchor hole. When subjected to vibratory loads, the Spike will expand due to the residual spring action of the expansion mechanism.
