Hollow wall anchor

  • Function: The grip wings distribute the load over a large surface and provide maximum durability without the need for additional reinforcements. The screw in the anchor can be replaced with another screw of the same diameter and thread. The hollow wall anchor is used for drywall and certain other board material.
  • Track type bit: Pozidrive 2 and 3/drives.
  • Material: Steel.
  • Coating: Zinc-plated 5 my, for indoor use.
  • Installation instructions: Drill a hole adapted to suit the size of the anchor as shown in the table below. Push the anchor into the hole and tighten using the expansion pliers. Now unscrew the screw and fit the fastening by re-fitting the same screw.
