OMG Heavy Duty Roofing Fasteners (#14) are designed to secure insulation and single-ply to heavy steel (18 – 22 Ga.), wood, and structural concrete decks. Available in lengths from 1 1/4-in. - 24-in. Factory Mutual and Dade County approved.
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.
Steel & Wood Decks - The fastener must penetrate steel and wood decks a minimum of 3/4-in.
Structural Concrete Decks - The fastener must penetrate structural concrete decks a minimum of 1-in. Pre-drill a 3/16-in. pilot hole at least 1/2-in. 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.
Prior to job-start, contact OMG to perform a pullout test to determine pullout values
NOTE: 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.
