Installed toilet rocking a tad

I know I can shim the toilet, but want to make sure why it is rocking is only floor related.

I installed a tile floor. The result has the toilet flange ~1/4" below floor level. I decided to use the Danco Perfect Seal instead of a wax ring. I used them two previous times with good results. This time the toilet is rocking a tiny bit. As I look at where the toilet is rocking it appears to be rocking or pivoting about the location of the Danco seal leading me to believe the seal is holding the toilet ever so slightly off the floor. The only other possibility is the flange bolts. The bolts would not lock in and just kept rotating when trying to tighten, I installed a nut and tightened the bolt to the flange (under the toilet), then installed the toilet followed by the usual washers and nuts. I am not sure if it may be hitting these nuts. I will look closely today

I guess I am looking for some help identifying the source of the rocking before blindly shimming the toilet.

That may be one reason it is rocking. You did use new bolts didn't you? They should have come with speed nuts or flat plastic discs that go on the bolt before the toilet to hold the bolt in place.

Yes, I did use the new bolts. The problem is the flange had been repaired using one of those stainless steel repair rings. The slots in it are large enough that the flats on the flange bolts will not lock the bolt from spinning. This is why I used a jam nut to tighten it to the flange, first.

Have you test-fitted the toilet with no wax ring and no Danco sealer and with all other necessary parts including the upright flange bolts and speed nuts in place? Don't screw down the cap nuts for now, of course. If you get any rocking you need to correct that before doing the final fitting with the Danco sealer.

The underside of the toilet must not touch the flange or any object in the vicinity of the flange.

Update- I looked closely at the seal and the lock nuts I had installed. Neither was the cause for the rocking. I went ahead with the shims and managed to eliminate the movement with a couple shims. All the worry for nothing. Thanks for the help.
