Product Use

Product Use

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.
