Description
The OMG CRH24 is a 24-inch #14 heavy duty roofing fastener designed for extremely thick roof insulation and membrane assemblies. Its deep thread geometry ensures superior pull-out resistance, while the 30° spade point provides fast penetration into steel, wood, or concrete. The CR-10 finish delivers long-term corrosion resistance.
Key Features:
-
Deep threads maximize pull-out resistance in roofing substrates
-
30° spade point allows rapid penetration into deck materials
-
CR-10 corrosion-resistant coating extends fastener life
-
#3 Phillips truss head compatible with screw guns
-
24-inch length accommodates the thickest roofing assemblies

How To
- Measure the total insulation and membrane thickness to determine correct fastener length plus embedment.
-
Drill a 3⁄16 in (5 mm) pilot hole at least ½ in (13 mm) deeper than embedment requirement.
-
Insert the fastener so the head is flush with the surface of the insulation, membrane, or plate.
-
Drive using a #3 Phillips bit until a slight depression forms around the plate; do not overdrive.
-
Confirm insulation boards and plates are flat and secure.
-
Conduct pull tests in representative areas to ensure performance.
FAQs
Q: Why use CRH24 instead of shorter fasteners?
A: CRH24 is made for the thickest roofing assemblies where shorter lengths cannot achieve embedment.
Q: What coating does CRH24 have?
A: CR-10 corrosion-resistant coating, the standard finish for OMG heavy duty fasteners.
Q: Which deck types are supported?
A: Steel, wood, and structural concrete when proper embedment and pilot drilling are followed.
Q: How many fasteners come in each box?
A: 500 per box.
Q: Should pull tests be performed?
A: Yes, pull tests are recommended to verify substrate anchorage and performance.
