Standard Roofing Fastener

The OMG Standard Roofing Fastener, (#12) is designed to secure insulation and single-ply to standard steel (18 ga. - 24 ga.) and wood.  It is available in lengths from 1 5/8" - 8".  The OMG Standard Roofing Fastener is Factory Mutual and Dade County approved.

Features & Benefits

  • Heavier shank & thread diameters than most "standard" roofing fasteners.
  • Deep buttress thread for high pullout resistance.
  • Extra sharp spade point for quick installation in new or reroof applications.
  • Available with hex head or #3 phillips truss head.

Application

The OMG Standard Roofing Fastener must penetrate steel decks a minimum of 3/4", wood plank decks a minimum of 1" and 1/2" through the underside for plywood decks.  Using a screwshooter, 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:  Care must be taken not to overdrive the fastener and fracture the skin of the insulation.  Fastener must be tight enough so that the plate doesn't turn.  For steel decks, Factory Mutual requires that the fastener penetrates the deck at the top flute.  To speed installation, this fastener is also available as a labor saving screw and plate.  See ASAP®.

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 upon the application.  See Plates section.  For best installation result, use a variable speed 0-2500 rpm screw gun.
