A mounting bolt for use in mounting toilet stools has upper and lower ends with an elongated threaded shank therebetween. An elongated planar head is on the lower end of the bolt and has a width similar to the diameter of the shank, and a longitudinal length larger than the diameter of the shank. The head has a center axis extending along its length. An indicia mark is on the upper end of the bolt visually indicating the position of the center axis to assist the placement and tightening of a threaded nut on the upper end when the position of the head is concealed when the nut is being threadably mounted on the upper end of the bolt.

1. A retainer ring for retaining a threaded bolt within an aperture in a support system, comprising, a flat solid flexible member of continuous construction having the flexible qualities of rubber or the like with a continuous unbroken center aperture having continuous uninterrupted threads extending around an interior surface of the aperture, the flexible member being sufficiently flexible to permit it to be longitudinally pushed onto the threaded shank of an elongated bolt of a threaded diameter the same as that of the threaded aperture in the flexible member and to thereupon engage the threads in the aperture in intimate operative rotational engagement therewith. 2. The retainer ring of claim 1 wherein the flat flexible member is thicker around the aperture therein to better permit space for the formation of threads in the aperture. 3. The retainer ring of claim 1 wherein ribs are formed on an upper surface of the flat flexible member for facilitating the manual rotation thereof when mounted on a threaded bolt.
