Heavy Duty Roofing Screw

The OMG Heavy Duty Roofing Fastener (#14) is designed to secure insulation and single-ply to heavy steel (0.7mm – 1.0mm), wood, and structural concrete decks. They are Factory Mutual approved, and come in lengths from 32mm - 610mm.

Features & Benefits 

  • Heavier shank & thread diameters than most “heavy duty” roofing fasteners.
  • Deep thread for high pullout resistance.
  • Extra sharp spade point for quick installation in new or reroof applications.
  • In concrete applications, fastener may be reversed out of predrilled hole without damaging the deck.

 Application

Steel & Wood Decks - The fastener must penetrate steel and wood decks a minimum of 20mm.

Structural Concrete Decks - The fastener must penetrate structural concrete decks a minimum of 25mm.  Pre-drill a 5.0mm pilot hole at least 12.5mm deeper than fastener embedment using a carbide tip SDS or straight shank bit.

Drive the fastener until a slight depression is seen around the plate, or with very rigid insulation boards, watch for the plate to dimple.

NOTE: Prior to job-start, contact MAK to perform a pullout test to determine pullout values.  Also, case must be taken not to overdrive the fastener causing subsequent damage to the insulation facer. The fastener must be tight enough so that the plate does not turn.

Coating

OMG CR-10 corrosion resistant coating exhibits less than 15% red rust after 30 Kesternich cycles.  CR-10 coating exceeds F.M. Approval Standard 4470.

Plates & Accessories

Use appropriate steel or plastic plates, depending on the application. See Plates section.
On structural concrete decks, use a 5.0mm carbide tip SDS or straight shank bit.
