Double Expansion Shields are a corrosion resistant anchor that is designed to be used with a machine bolt in concrete, brick, block, and stone. The anchor comes pre-assembled and consists of a zamac alloy anchor body, 2 expansion cones (1 at each end of the anchor), and a wire expanding ring that holds the entire anchor together. The expansion cones are drawn in at each end of the anchor as the machine bolt is tightened into the anchor – ensuring consistent and even expansion along the entire anchor body. Recommended for anchoring into base materials of questionable strength.
- Eliminates high stress points that can be detrimental in fastening into materials of medium hardness
- Expands fully to provide high gripping power
- Ideal for shear loads where joint is subject to side pressure or vibration
- Corrosion resistant body
