Daggerz™ Lo-PRO Clip Screws are available in a variety of types, sizes, and materials. Lo-PRO Screws have a pancake style head design which allows more bearing surface for greater strength where a lower profile head is desired. The Ultra Lo-PRO head has an even lower profile when needed. Clip Screws are available with a type 17 or Gimlet point and are recommended for fastening pre-punched roofing clips to wood or light gauge metal.
