Assembled Wind-Devil 2 Fasteners with Self-Tapping Masonry Screws are ideal for securing EPS Foam Insulation to Masonry or Concrete. Easy to install. Use a hammer drill with a 5/32 bit to drill a clean pilot hole into the base material. Clear the hole of any excess debris, insert the screw and tighten. To prevent stripping of the base material be sure to tighten the screw slowly and avoid over-torque.
