Abstract
A nut assembly comprises a capture nut having a smooth bore adapted to fit around the threads of a threaded member such as a bolt or a threaded rod. The capture nut includes a tapered bowl which defines a hexagon in cross section, for example. The nut assembly further includes a split nut having a surface which snugly mates with the tapered bowl of the capture nut. The split nut engages the threads of the threaded member, but only after the split nut is brought into close proximity to the capture nut, thereby avoiding the need to thread the nut assembly the entire length of the threads of the threaded member. The split nut may be formed to two separable pieces, or it may be formed of two integral halves joined together by a thin membrane.

A nut assembly arranged for mounting on a threaded member, the nut assembly comprising:
- a. an axially oriented capture nut comprising:
- i. an outer, wrench-engaging surface;
- ii. a bowl defining a plurality of slanted surfaces;
- and
- iii. a bore through the bowl on the axis of the capture nut for passing a threaded member through the capture nut;
- b. a pair of opposed nut halves comprising:
- i. a bottom surface for mating engagement with the bowl of the capture nut;
- and
- ii. an internally threaded bore, coaxial with the bore of the capture nut, for engagement with the threaded member;
- and
- c. a removable tube arranged to fit between the nut halves and the threaded member until removed.
