Description
The OMG XHD018 is an 18-inch #15 Extra Heavy Duty roofing fastener designed for extra-thick insulation and membrane systems attached to light gauge steel, OSB, plywood, or aluminum decks. Its oversized shank and threads maximize pull-out strength. Deep buttress threads minimize pull-out and back-out, while a miniature drill point ensures quick penetration. The CR-10 coating provides long-term corrosion protection.
Key Features:

Oversized shank and threads provide superior pull-out resistance
-
Deep buttress thread design reduces pull-out and back-out
-
Miniature drill point for fast penetration into substrates
