摘要： An improved slide-fit nut is provided for rapid push-on mounting to a substantially seated position on a threaded bolt or the like. The slide-fit nut includes a plurality of threaded nut segments carried within a nut housing and adapted for radial expansion to accommodate push-on mounting onto a threaded bolt. A cap plate on the nut housing includes cam members for retaining the nut segments in threaded engagement with the bolt upon rotation of the nut in a tightening direction. When the nut is rotated in an opposite direction, the cam members displace the nut segments in a radially outward direction relative to the bolt, resulting in substantial disengagement of the nut segments to permit rapid pull-off removal of the nut from the bolt.
