Abstract
Disclosed are new thread profiles that provide multi-point contact improving the vibration resistance of the threaded fastener, and thereby greatly reducing the need for fastener coatings, such as nylon patches. In various embodiments, the threaded faster may have a threaded portion configured to engage two or three points of a mating thread, and the threaded portion has a thread defined by a crest portion, a leading flank, at least one root portion, and a trailing flank, all of which may be oriented at angle relative to the normal axis.
