Fast-Installing Collated Fastener

Grip-Rite SpeedSpikes are 4 ½-inch collated fasteners for installing high R-value insulated exterior sheathing. The manufacturer says that they can be driven through the sheathing and rigid foam layers in a single shot with full 2-inch stud embedment, and that they reduce installation time to one-fifth that of hand-driven fasteners. The ring shank design ensures secure grip in wood studs. The SpeedSpike is designed for use with 21-degree heavy-duty timber framing nailers. grip-rite.com
