A pitch break connector is provided. The pitch break connector has an outside and inside rigid member. Each member has a first generally U-shaped channel defined by a spine member between first and second legs. Each member has a first and a second pivot end portion. A hinge pivotally connects the inside and outside members through the pivot end portions in a generally longitudinally opposing position. In this configuration, the first and second end portions of the inside member can be pivotally accepted into a cavity defined by the generally U-shaped channel of the outside member when the members are pivoted about the hinge.

An improved fastener securing framing members to metal studs is provided. The fastener has rigid shank, an integral head, a self-tapping or drilling tip, and a first and a second spaced apart buttress threads. The shank has a generally circular cross-section and a longitudinally extending axis. The head integrally extends a first end of the shank and has a top portion and an underside. The self-drilling tip is extends from a second end of the shank. The first buttress thread is formed in said shank and is adjacent the head and partially traverses the shank, terminating from the shank's second end. The second buttress thread is formed in the shank and sufficiently spaced apart from the first buttress thread such that the first thread does not continue to threadingly feed the shank through an aperture formed by the self-drilling tip, the second buttress thread terminating adjacent the tip.

Dual threaded fastener and metal component assembly

An integral, one-piece, metallic chord for use as the top and bottom chords of a roof truss. The chord comprises an elongated member of generally U-shaped, singly symmetric cross-section, having a base terminating at its longitudinal edges in mirror image legs. The base portion is planar with a central depressed rib formed therein and extending the length thereof. Each leg comprises a first planar portion perpendicular to and extending from its respective longitudinal edge of the base, followed by an inwardly sloped planar portion leading to a planar attachment portion which is perpendicular to the base portion and which terminates in a flange portion extending outwardly of the attachment portion and then upwardly and inwardly, ending in a longitudinal edge facing the attachment portion. The flange portions form semi-closed reinforcement members. The legs and their flange portions constitute the sides of the chord. The first planar portion of each leg and the outermost part of the flange portion of each leg are co-planar, so that the chord will lie flat on either of its sides.
