The OMG Standard RoofGrip Drill Point Fastener must penetrate steel decks a minimum of 3/4-in., wood plank decks a minimum of 1-in. and 1/2-in. through the underside for plywood decks. Using a screw gun,* drive the fastener until a slight depression is seen around the plate.
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 can be used with the AccuTrac® System and is also available pre-assembled. See AccuTrac or ASAP®.
