A segmented nut has inner segments and an outer sleeve. Part of the sleeve interface portion and part of the segment interface portion engage when the sleeve rotates relative to the inner nut during release of the segmented nut with part of the segment interface portion at a greater distance from a central axis of the segmented nut than a minimum distance of the at least part of the sleeve interface portion from the central axis. One or more of the segments can include a retainer preventing the sleeve moving toward a free face of the segment(s). One or more of the segments can have a flange portion providing an increased working (compression) face relative to a plain segmented nut. An assembled segmented nut can include some radial freeplay for the segments to move radially whilst being retained within the sleeve prior to application of the segmented nut to a threaded bolt, stud or rod such that threading of the segmented nut onto the thread of the bolt, stud or rod removes the freeplay.
A segmented nut for threaded engagement with a threaded shaft of a bolt, stud or rod, the segmented nut including an inner nut including at least three segments providing at least a portion of a threaded aperture through the inner nut for engagement with the threaded shaft of the bolt, stud or rod, each of the at least three segments having at least one segment interface portion, and a sleeve engaging around and retaining together the at least three segments when the segmented nut is assembled, the sleeve including a sleeve interface portion,
A segmented nut for threaded engagement with a threaded shaft of a bolt, stud or rod, the segmented nut including an inner nut including at least two segments providing at least a portion of a threaded aperture through the inner nut for engagement with the threaded shaft of the bolt, stud or rod, at least one of the at least two segments including at least two segment interface portions and a remainder of the at least two segments each including at least one segment interface portion, and a sleeve engaging around and retaining together the at least two segments when the segmented nut is assembled, the sleeve having an inner surface providing a sleeve interface portion, at least one of the sleeve interface portion and a respective segment interface portion undergoing resilient deformation through contact of the sleeve interface portion and the respective segment interface portion during relative rotation of the sleeve and inner nut as the sleeve interface portion and the segment interface portions pass one another during release of the segmented nut, wherein the segmented nut comprises at least one axial retainer provided on the inner nut, the axial retainer being configured to restrict removal of the sleeve from the at least two segments in at least one axial direction, the at least one axial retainer being adjacent a working face of the inner nut or adjacent to a free face of the sleeve distal from the working face of the inner nut, the at least one axial retainer allowing the sleeve to release and separate from the inner nut when the sleeve is rotated to a sleeve release orientation relative to the inner nut.
