About Drill-Tec™ SXHD Fasteners (#21)

Drill-Tec™ SXHD Fasteners (#21) have over-sized heavy shank and thread diameters for enhanced pull-out resistance in light-gauge metal roof decks to secure single-ply membrane to 22 gauge or higher metal decks.

  • Deep buttress threads further increase pull-out resistance
  • Miniature drill point penetrates decks quickly and contributes to exceptional resistance to back-out as well as pull-out.
