Tamper-Proof Spike Anchors

Pre-Expanded Anchors

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. 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.

Installation

  • Drill a hole into the base material to a depth of at least 1/2" deeper than the embedment required. The tolerances of the drill bit used should meet the requirements of ANSI Standard B212.15.
  • Blow the hole clean of dust and other material.
  • Where a fixture is used, drive the anchor through the fixture into the anchor hole until the head is firmly seated against the fixture.
  • Be sure the anchor is driven to the required embedment depth.
