The OMG Heavy Duty Roofing Fastener (#14) is designed to secure insulation and single-ply to heavy steel (18 – 22 ga.), wood, and structural concrete decks. They are Factory Mutual and Miami Dade County approved, and come in lengths from 1 1/4 - 24".
Steel & Wood Decks - The fastener must penetrate steel and wood decks a minimum of 3/4".
Structural Concrete Decks - The fastener must penetrate structural concrete decks a minimum of 1". Pre-drill a 3/16" pilot hole at least 1/2" 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 OMG to perform a pullout test to determine pullout values. Also, care 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.
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.
Use appropriate steel or plastic plates, depending on the application. See Plates section. On structural concrete decks, use a 3/16" carbide tip SDS or straight shank bit.
Longer lengths available upon request. Call OMG for information.
