Concrete Anchors

Available in steel and 303 stainless steel

Concrete Wedge Anchor Installation

A single one piece spring steel band is locked into position by tongues. These tongues act like fish hooks
which penetrate into the concrete. The required 3 to 4 turnes of the nut cause the outward taper to move
upward with the wedge expanding in fixed position.

  • The ideal anchor for use in concrete where excellent holding power is required.
  • Eliminates drilling costly oversize holes - Thread diameter equals hole diameter.
  • No need for exact hole depth - Hole bottom not required to set anchor.
  • Anchorage occurs near bottom of hole giving a true 360° of contact.
  • Predrilled fixtures can be anchored in place without moving back and forth.
  • Saves time on every job - Increases worker efficiency.

How to install

1. Drill hole in concrete (hole dia. same as thread dia.) maximum depth of hole could be any depth beyond minimum recommended depth. 2. Drive wedge anchor into drilled hole through fixture so that nut is flush with fixture. 3. Tighten nut until wrench resistance is felt (approximately 3 to 4 turns of the nut after snugged up) anchorage is now complete.
