ABSTRACT:
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.
