ABSTRACT:
A novel nosepiece for a fastener driving tool for driving fasteners for holding and spacing an object at a predetermined distance from a substrate are provided, wherein the fastener driving tool has a housing, a driver blade within the housing for driving the fasteners, and a power source for driving the driver blade, and each of the fasteners includes a bridge portion, a first prong extending in a driving direction from the bridge portion, a second prong spaced from the first prong and extending generally parallel thereto in the driving direction from the bridge portion, wherein the second prong is substantially shorter than the first prong, the nosepiece comprising, a trailing end coupled to the housing of the fastener driving tool, a substrate contacting end, a channel for axially guiding the driver blade and the fastener in a driving direction toward the substrate, a slot proximate the substrate contacting end laterally extending into the channel for receiving the object, and a curved ramp within the channel, wherein a portion of the ramp is positioned between the slot and the substrate contacting end, the ramp being for interfering with the path of the second prong to bend the second prong toward the first prong to hold the object between the second prong and the bridge portion.
