Double Expansion Masonry Anchors

Zamak Zinc Alloy Concrete Anchors for Masonry Screws or Bolts

Zamak Zinc Alloy
Four Part design: a two-piece tubular shield, a hollow, wedge-shaped cone and a wedge-shaped nut-- brought together into a single anchor unit
Used in soft masonry with machine screws or machine bolts
Can also be used in harder materials, including stone, brick, concrete or block
Expansion of the band or shield occurs during installation
For applications that deal in shear loads or where the bolts are subjected to pressure or vibration

A Double Expansion Shield Anchor is suited to anchor into materials of questionable strength such as materials that may be soft or of low quality. This is due to the design of the double expansion anchor as it expands upon its entire length, maximizing friction and holding power even in low quality or suspect materials. Can be used in brick, block, and stone as well.
