1. An installation tool for fastening a first member to a second member comprising:
- a driver assembly comprising an elongated tube assembly having a proximal end and a distal end, a driver which generates torque mounted adjacent said proximal end and a torque transfer unit disposed in said tube for transferring torque produced by said driver to a fastener coupler adjacent said distal end; and
a guide assembly mounted adjacent said distal end and having a locating end and a non-coplanar locating surface and a fastener channel defining an axis disposed at an angle θ
of approximately 22½
°
to said locating surface and configured to receive a fastener so that when said locating surface is positioned against said first member, said locating end is positioned adjacent said second member, said fastener is received in said channel, and said driver is energized, said fastener coupler engages said fastener and is torqued to drive said fastener through said first member at said angle θ
into said second member.

Abstract
An installation tool for fastening a top plate to a roof support member and other structural connections is adapted to drive screws at a pre-established angle. The tool preferably includes a rotary driver assembly and a telescopic tube assembly. A guide assembly is mounted adjacent the outer end of the telescopic tube assembly. Locating structures function to properly precisely set the drive angle of the screw. A stabilizer prevents the screw from moving during the installation. The guide assembly is also configured to provide a marking for inspection purposes.

11. An installation tool for fastening a top plate to a roof support member comprising:
-
a transfer assembly comprising an elongated telescopic tube assembly having a proximal end portion and a distal end, said proximal end portion adapted to receive a power tool and a torque transfer unit disposed in said tube assembly which transfers torque produced by said power tool to a fastener coupler adjacent said distal end; and a guide assembly mounted at said distal end and having a locating surface and a locating end and a fastener channel defining an axis disposed at an acute angle θ
less than 45°
to said locating surface and configured to receive a fastener so that when said locating surface is positioned relative said top plate, said locating end is positioned proximate said roof support member, said fastener is received in said channel and a received tool is energized, said fastener coupler engages said fastener and is torqued to drive said fastener through said top plate at said angle θ
into said roof support member. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. An installation tool for fastening a first member to a second member comprising:
-
a driver assembly comprising an elongated tube assembly having a first end and a second end, a power driver for applying torque mounted adjacent said first end and a torque transfer unit defining a torque axis disposed in said tube which transfers torque produced by said power driver to a fastener coupler adjacent said second end; an adjustable handle assembly mounted to said tube assembly; and a guide assembly mounted adjacent said second end and having a locating surface and a fastener channel defining an axis disposed at an acute angle θ
less than 45°
to said locating surface and coaxial with said torque axis and configured to receive a fastener and a locating end having a projecting member so that when said locating surface is engaged against said first member, said projecting member engages into said second member, said fastener is received in said channel and said power driver is energized, said fastener coupler engages said fastener and is torqued to drive said fastener through said first member at said angle θ
into said second member. - View Dependent Claims (21, 22, 23, 24, 25)
