A self-drilling bolt and nut assembly includes a nut which has a window to permit visual inspection of the fastener thread upon engagement with the nut. The nut also includes a protective cap or receives a protective cap so that upon threadably engaging the fastener with the nut, the drill tip of the fastener is automatically received in the cap. The nut also has at one end a plurality of projections to enhance the locking engagement. The self-drilling bolt may have an integral washer and employ a clamping plate engageable against the washer.

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.
