ABSTRACT:
A simplified nut having a substitute "thread" in the form of an edged flat which can receive a threaded member. The flat or flats are swedged from material preferably in sheet form surrounding a smooth bore opening in which the flat(s) entirely extend. The edges of the flat(s) may be circular or helical, continuous or discontinuous. The device and its forming method eliminates separate handling and cleanup associated with conventional thread forming methods.
