Description
The OMG CRH10B is a 10-inch #14 heavy duty roofing fastener engineered to secure insulation and membranes to structural decks. It has deep threads to enhance pull-out resistance. The CR-10 finish provides corrosion protection, and its spade point enables effective penetration.
Key Features:
-
Deep thread profile for high pull-out resistance
-
30° spade point for swift penetration
-
CR-10 corrosion-resistant coating to protect from environmental exposure
-
#3 Phillips truss head compatible with standard roofing screw guns
-
10-inch length supports thick roof assemblies

How To
- Determine required fastener length by summing insulation + membrane thickness plus the embedment requirement.
-
Drill a 3⁄16 in (5 mm) pilot hole at least ½ in (13 mm) deeper than the embedment depth.
-
Position the fastener so the head is flush with the membrane, insulation, or plate surface.
-
Drive the fastener using a #3 Phillips bit until a slight depression forms around the plate; avoid overdriving.
-
Ensure the plate and insulation lie flat and stable before final driving.
-
Conduct pull tests at representative locations to validate anchorage performance.
FAQs
