Abstract: 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.

Abstract: A floor mounting system for toilet stools has a retaining nut to stabilize the vertical mounted flange bolts to facilitate the lowering of a toilet stool into the vertical bolts. When in position, caps are screwed into a retaining washer on the upper ends of the mounting flange bolts to stabilize the caps, and to protect the bolts against contact with exterior moisture. Internal threads within the cap are threadably mounted on exterior threads on the retaining washer.
