Description
The OMG CRH12B is a 12-inch #14 heavy duty roofing fastener for securing insulation and membranes to common roof decks. Deep thread geometry provides strong pull-out resistance. A 30° spade point speeds penetration and the CR-10 finish delivers corrosion resistance.
Key Features:
-
Deep thread profile for high pull-out resistance
-
30° spade point for rapid penetration and fast starts
-
CR-10 corrosion-resistant coating for durability
-
#3 Phillips truss head compatible with standard screw guns
-
12-inch length accommodates thicker assemblies

How To
- Determine required fastener length using assembly thickness plus minimum embedment.
-
Drill a 3⁄16 in (5 mm) pilot hole at least ½ in (13 mm) deeper than the embedment depth as required.
-
Place the fastener so the head sits flush with the plate, insulation, or membrane surface.
-
Drive using a #3 Phillips bit until a slight depression forms around the plate; do not overdrive.
-
Verify plates and boards are flat and secure, then perform representative pull tests.
