A bolt assembly for use with toilet seats and other objects consists of a threaded bolt with a threaded axial bore and a head larger than the opening in the toilet bowl flange, a nut sized to fit the bolt, and a screw dimensioned to cooperate with the bore. The bolt is inserted through the opening in the flange, extending there beyond. The bolt is secured from below the flange with the nut. The seat assembly is then placed on the flange so that the aperture in the seat assembly bracket communicates with the threaded bore. The seat assembly is secured in place by passing the screw through the aperture in the bracket and threading it into the bore. The seat assembly can then be reversibly removed for cleaning by merely removing and replacing the screw without having to reach under the flange. The screw can have a gripping head so that it can be rotated without the need for a screwdriver, or there can be a slot centered on the top of the head so that a screwdriver can be used. The slot can be sized to accept a screwdriver but such that it will not permit the screwdriver to slip sideways during use.
