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 int o 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.
