Description
The OMG CRH22 is a 22-inch #14 heavy duty roofing fastener engineered for the thickest insulation and roofing systems. Its deep thread profile maximizes pull-out resistance, while the 30° spade point delivers quick penetration into steel, wood, and concrete decks. The CR-10 coating provides superior corrosion resistance in demanding environments.
Key Features:
-
Deep thread geometry designed for maximum pull-out strength
-
30° spade point for fast, reliable penetration
-
CR-10 corrosion-resistant coating extends service life
-
#3 Phillips truss head works with standard roofing screw guns
-
22-inch length supports ultra-thick roofing assemblies

How To
- Measure total thickness of insulation and membrane to determine fastener length plus embedment requirement.
-
Drill a 3⁄16 in (5 mm) pilot hole at least ½ in (13 mm) deeper than embedment.
-
Place the fastener so the head sits flush against the plate, insulation, or membrane.
-
Drive using a #3 Phillips bit until a slight depression forms around the plate; do not overdrive.
-
Ensure all plates and boards are flat and secure.
-
Perform pull tests in representative locations to verify anchorage performance.
FAQs
Q: Why would I use CRH22 instead of a shorter fastener?
A: CRH22 is designed for ultra-thick roofing assemblies where shorter fasteners cannot meet embedment requirements.
Q: What protective coating is on CRH22?
A: It uses CR-10 corrosion-resistant coating, standard for OMG heavy duty fasteners.
Q: Which substrates are suitable for CRH22?
A: Steel decks, wood decks, and structural concrete with proper embedment and pilot drilling.
Q: How many fasteners come in one box?
A: 500 per box.
Q: Are pull tests required?
A: Yes, pull tests are recommended to ensure anchorage in the actual substrate.
