Description
The OMG CRH14 is a 14-inch #14 heavy duty roofing fastener designed to fasten membrane or insulation through deep roof assemblies. It features aggressive deep thread geometry to maximize pull-out resistance. The 30° spade point ensures easy penetration, while the CR-10 coating offers environmental durability.
Key Features:
-
Deep thread design to maximize pull-out strength
-
30° spade point to allow smooth penetration
-
CR-10 corrosion resistant coating to extend longevity
-
#3 Phillips truss head for compatibility with standard screw drivers
-
14-inch length supports thick multilayer roof systems

How To
- Determine fastener length according to total thickness plus minimum embedment requirement.
-
Drill a 3⁄16 in (5 mm) pilot hole that is at least ½ in (13 mm) deeper than the embedment.
-
Position the fastener so its head is flush to the membrane or substrate surface.
-
Drive using a #3 Phillips bit until a slight depression forms around the plate, without overdriving.
-
Ensure plates or insulation are flat and stable before final drive.
-
Perform pull tests in representative areas to verify anchorage performance.
FAQs
Q: Why choose CRH14 over shorter fasteners?
A: CRH14 accommodates much thicker insulation or membrane systems while maintaining required embedment.
Q: What coating is applied on CRH14?
A: It uses CR-10 corrosion-resistant coating standard for OMG heavy duty screws.
Q: Which substrate types are supported?
A: Steel decks, wood decks, and structural concrete when proper embedment and pilot drilling are observed.
Q: What pilot hole size is recommended?
A: 3⁄16 inch (5 mm), drilled at least ½ inch deeper than embedment depth.
Q: Is it necessary to perform pull tests?
A: Yes, pull tests are recommended to validate performance in the exact substrate conditions.
