This can cause an issue with less than the best seal between the toilet drain and the closet ring resulting in leaks at the base of the toilet. Whether a new install or re-seating of a toilet, I only use these extra thick reinforced wax rings. They provide the extra wax needed to bridge the gap between toilet and closet ring. With included flange bolts, a proper installation with a good. no-leak seal is ensured. The only thing I would suggest is using 2 of the old flange nuts and washers to "lock" the new flange bolt onto the closet ring by adding the bolt above the closet ring and tightening it against the top of the closet ring. (see drawing). This helps maintain the flange bolt tightness so if and when it needs to be removed, it won't just "spin" while loosening the toilet hold down nuts. *** One more note *** I NEVER use sealant to seal or "hold" the toilet to the floor. What this can do is hide any leaks in the wax seal. If there is a hidden leak for an extended time, the water damage caused in the floor or substructure can be very expensive to repair...
