Wedge Anchors

Concast wedge anchors can be used in the FPS style solid concrete flat pads, or in other applications as well.   They feature a single piece expansion clip, a threaded stud bolt body, integral cone expander, nut and washer.   Anchor bodies are made of zinc plated carbon steel or stainless steel.  See below for anchor installation instructions.

  • Holes in metal fixtures to be mounted should exceed nominal anchor diameter by 1/16".

  • Do not use an impact wrench to set or tighten wedge anchor.

  • Caution: Oversized holes in the base material will make it difficult to set the anchor and will reduce the anchor's load capacity.
