A fastener driving tool includes a driver having a driver shaft extending therefrom, a first extension member operably connected to the driver and a second extension member operably connected to the first extension member. The tool is for use on roof deck panels. The second extension member slidingly engages the first extension member between a loading position and a driving position. A bearing assembly operably connects the first and second extension members. The bearing assembly is formed from a non-metallic, low-friction material. A portion of the bearing assembly is mounted to one of the first and second extension members for sliding engagement with the other extension member and is disposed to prevent direct contact of the first and second extension members with one another. A fastener receiving member is mounted to the second extension member for receiving fasteners when in the loading position and for supporting and releasing the fasteners when in the driving position. The fastener receiving member includes a cradle having a main body portion and a pair of legs extending from the main body portion diverging downwardly and outwardly. The cradle is configured for positioning on the roof panel, straddling raised portions of the panel for aligning the tool therealong.

A support device for use within a fastener driving tool is fixedly attached to the tool's workpiece contact element so as to be movable therewith between extended and retracted positions. When the workpiece contact element, and the support device mounted thereon, are moved to the retracted position, a pocket or recessed portion of the support device will envelop a tip portion of a second uppermost fastener disposed within the tool magazine, while the first uppermost fastener is disposed within the tool drive bore, such that the second uppermost fastener, as well as the remaining fasteners within the magazine, is properly supported and stabilized such that shock and vibrational forces, attendant the driving of the first uppermost fastener, are effectively prevented from being transmitted to the second uppermost and remaining fasteners. In addition, the pocket or recessed portion serves to partially close the magazine opening through which the fasteners are serially advanced such that the first uppermost fastener will be maintained coaxially aligned within the tool drive bore, and an upstream leading edge of the pocket or recessed portion also defines a shearing edge for properly shearing those portions of the collation strip which interconnect adjacent pairs of the fasteners within the collated strip of fasteners.

An attachment implement, for use in connection with the mounting of a relatively thin, highly dense insulation panel upon an underlying structural substrate, comprises a washer plate portion and an integral lower body portion which has a substantially inverted dome-shaped or bell-shaped configuration. The axial depth dimension of the implement is relatively shallow or small, and the inverted dome-shaped or bell-shaped configuration advantageously distributes or disperses the compressive forces attendant the mounting of the insulation panel upon the underlying structural substrate whereby desired compression of the insulation panel, and its rigidifying or strength-enhancing membrane, occurs without tearing or cutting of the insulation panel and its membrane so as not to adversely affect the strength, rigidity, and structural integrity of the insulation panel.
