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.
