Abstract of the Disclosure A swivel assembly comprising a base plate, a swivel plate mounted on the base plate for rotation relative thereto, bearing elements between the opposing inner faces of the plates, and a fastener connecting the plates. The fastener comprises a bolt having a head on the outer face of the base plate, and a threaded shank extending through axially aligned holes in the plates. The fastener further comprises a nut on the outer face of the swivel plate threaded on the bolt for drawing the swivel plate toward the base plate against the bearing elements. Both the head of the bolt and the nut are freely rotatable relative to the plates, with the head of the bolt being generally accessible for being turned, and the nut being rendered generally inaccessible by an object mounted on the outer face of the swivel plate. A lock selectively holds the nut in fixed angular position relative to the swivel plate to ensure relative rotation of the nut and bolt upon turning the head of the bolt, whereby the resistance of the swivel plate to rotation relative to the base plate may be adjusted.
