Abstract
A quick coupling nut includes a body having a bore therethrough and adjacent side holes. A pair of threaded members are disposed in the bore and moveable in a radial direction of the bore and a cap having a bore therethrough, coaxial with the body bore, includes depending guides which are received by the guide holes for enabling axial movement between the cap and the body. Actuators depending from the cap engage the threaded members in order to urge the threaded members radially inward to engage a threaded bolt shank, extending through the cap and body bores, as the cap is moved axially toward the body. This threaded engagements enables tightening of the quick coupling cap by rotation about the threaded bolt shank.
