Besides, concrete screws can be removed without damaging the base materials after installing. These screws can also be installed close to the edge.
Different lengths allow the screws to be used in many applications including: studs, plywood, electrical boxes, and exterior insulation systems. 
They can also be used for fixing window or door frames manufactured from wood, plastic or metal to concrete, brick, hollow brick or man-made blocks.

Installation Steps

  1. Measure the thickness of the material you will fasten to the concrete. Then choose a screw that is 1 to 1.75 inch longer than the thickness of the material.
  2. Choose a drill bit that is suitable for the screws. The diameter of the drill bit should be a little smaller than the screws.
  3. Measure the length of the screw. Then wrap the tape on the drill bit to mark the length of the screw. The tape can avoid drilling too deep in the concrete.
  4. Drill the hole until you reach the tape.
  5. Clean out the excess material from the hole with a wire brush and a vacuum.
  6. Set the material over the hole, and then screw the material into the concrete.
