OMG Extra Heavy Duty Roofing Fastener (#15) is a high-performance fastener with deep buttress threads for maximum pullout resistance. XHDs are designed to secure insulation and membrane to steel (20 and 22 Ga.), wood, OSB wood plank, and aluminum roof decks.
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.
Prior to job start, contact OMG to perform a pull out test to determine deck suitability and pullout values.
For steel and aluminum decks, ¾-in. penetration is the minimum allowable. Factory Mutual requires that fasteners penetrate the top flute.
For OSB and plywood, ¾-in. penetration through the underside of the board is the minimum allowable. For wood deck (wood beams, wood plank, tongue & groove), 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.
