An improved axial-on threaded coupling device is provided for push-on mounting to a substantially seated position on a male threaded member. The device includes a plurality of threaded coupling segments collectively forming a female threaded bore within a housing and configured for radial expansion to accommodate push-on mounting onto a male threaded member. When the device is rotated in a tightening direction, the segments are retained in threaded engagement with the male threaded member by the inner wall surfaces of the housing. When the device is rotated in an opposite direction, the fastener segments are free to expand radially outward to accommodate pull-off removal of the device from the male threaded member. |
