Abstract

See full text

A drive nut has a hollow interior in which a plurality of cantilever clamping members which are arranged with equal spacing around a common circle and extend substantially parallel to the nut centerline, and which are rigidly and integrally fixed at their lower ends to the nut inner side near the bottom seating surface thereof. The clamping members thus form a substantially cylindrical passage through which a mating member with a male screw thread is forcibly driven axially from the side of the seating surface relative to the nut to be quickly but positively locked by the drive nut.
