A fastener subassembly for being driven by a power actuated tool comprises a flute having a body and a pin having a tip for being driven into a substrate. The body of the flute has a longitudinal axis, a muzzle loading end, a mounting end, and a hollow bore. The pin is mounted in the bore with its tip proximate the mounting end, such that the tip is protected from pressure between the fastener subassembly and the substrate prior to driving. The mounting end of the flute has wings that extend radially outwardly. The wings allow the subassembly to be mounted in a hole in any suitable member that needs to be attached to a substrate while holding the pin substantially perpendicular to the substrate during driving.
