Features & Benfits

  • Oversized heavy shank and thread diameters for enhanced pullout resistance in light gauge steel and aluminum roof decks.
  • Miniature drill point penetrates decks quickly and contributes to exceptional resistance to back out as well as pullout.
Product Use

Product Use

For steel and aluminum decks, 20 mm (¾-in.) penetration is the minimum allowable. Factory Mutual requires that fasteners penetrate the top flute.

For OSB and plywood, 20 mm (¾-in.) penetration through the underside of the board is the minimum allowable. For wood deck (wood beams, wood plank, tongue & groove), 25 mm (1-in.) embedment is the minimum allowable.

Avoid overdriving the fastener. Fastener must be tight enough so that the plate doesn’t turn. For best results, use a variable speed 0-2500 RPM screw gun.
