Fastener for Installation Tool for Roof Truss Framing and Construction System

摘要

An installation tool fastener is particularly adapted for fastening a top plate to a roof support member and other structural connections and is particularly adapted for use with an installation tool. The installation tool fastener has a head with a maximum head diameter and a recess for coupling with a drive coupler. The shank of the head has an unthreaded portion and a uniform thread which has a major diameter approximately equal to the maximum diameter of the head. The head preferably has a slight taper. The thread preferably has a 7.5 thread per inch pitch and a thread angle from approximately 25° to 45°. In one embodiment for a 6 inch fastener, the thread length is approximately 5 inches and extends along the tapered distal tip.
