Description
The OMG CRH20 is a 20-inch #14 heavy duty roofing fastener engineered for the thickest insulation and roofing systems. Its deep thread design provides maximum pull-out resistance, while the 30° spade point ensures rapid penetration into steel, wood, or concrete decks. The CR-10 corrosion-resistant coating enhances durability and service life.
Key Features:
-
Deep threads designed for high pull-out resistance
-
30° spade point for fast penetration into substrates
-
CR-10 corrosion-resistant coating extends longevity
-
#3 Phillips truss head compatible with roofing screw guns
-
20-inch length accommodates the thickest roofing assemblies

How To
- Determine required fastener length by adding insulation and membrane thickness plus minimum embedment.
-
Drill a 3⁄16 in (5 mm) pilot hole at least ½ in (13 mm) deeper than embedment depth.
-
Insert the fastener so the head sits flush with the insulation, membrane, or plate surface.
-
Drive using a #3 Phillips bit until a slight depression forms around the plate; avoid overdriving.
-
Confirm insulation and plates are flat and secure before final drive.
-
Conduct representative pull tests to validate anchorage and substrate conditions.
FAQs
Q: What is the main benefit of CRH20 compared to other lengths?
A: CRH20 is designed for extremely thick roofing assemblies where shorter fasteners cannot achieve required embedment.
Q: What coating is used on CRH20?
A: CR-10 corrosion-resistant coating, standard across OMG heavy duty fasteners.
Q: What deck types can CRH20 be installed in?
A: Steel, wood, and structural concrete, when proper embedment and pilot drilling are used.
Q: How many fasteners are packaged per box?
A: 500 per box.
Q: Should pull tests be performed with CRH20?
A: Yes, pull tests are always recommended to confirm proper anchorage in the intended substrate.
