Wall driller anchor is made of nylon or Zamak. Its design is unique. The anchor has two shapes: the one has a single point and the other has two small points and a bigger point. The point is used to drill a hole, and the tapered, oversize head is to seal the hole. Because of this design, the wall driller can keep the consistency of the drywall. It is used to fasten in drywall for light duty, and there is no need to drill a hole advanced. The wall driller is of two different sizes-– #6 or #8. Wall driller anchor isn't used alone, it should be used with the correctly size metal screw.
