Masonry screws are used with anchors when fastening fixtures to concrete or masonry. Masonry screws and anchors work by expanding the anchor against the sides of the hole. Working with masonry isn't that difficult, but does require the use of specialized equipment to be successful.

  1. 1

    Drill the pilot hole. Be sure to follow the manufacturer's instructions for drilling the right hole size. Use a carbide tip drill bit to ensure that the hole is not larger than it should be.

  2. 2

    Clear debris by blowing out the hole. Be sure to wear protective eye gear during this process to prevent serious injury, both during the drilling and when clearing the debris.

  3. 3

    Drill a clearance hole in the fixture if the fastener requires it. This will usually be 1/16 inch larger than the anchor size.

  4. 4

    Install the fastener. For a one step anchor, place the fixture over your pilot hole, then gently tap the anchor into the pilot hole. For a two step anchor, gently tap the anchor into the pilot hole and then place the fixture into position. Drill the fastener into the anchor.

Tips and warnings

  • Success is determined by drilling the proper pilot hole size. Use the drill bit size recommended by the manufacturer.
  • Always use a sharp drill bit. A dull bit can make the pilot hole larger than it should be, making the fixture unstable.
  • Use the correct fastener for the job, and spread the load by using the right number of fasteners.
  • A hammer drill should be bought if you have many masonry drilling jobs.
  • Always wear protective eye gear when drilling into masonry as drill bits can shatter.
