Bolt on wall mounted toilet came out of wall

[Barry McKaig]

When we took the wall mounted unit off the wall, one of the bolts came with it. Is their a special epoxy we can use to help secure it?

The threaded rod goes into the carrier mounted to the wall studs.
There should be a locking nut that keeps the threaded rod from coming loose in the wall.
If the threaded rod is the correct length, you may be able to expoxy it as a locking measure instead of using the nut.
I've never done that, but it's worth a shot.

is this a residential toilet or a commercial toilet? Do you mean when you backed off the mounting nut the threaded rod came out with it? You should be able to screw it back in. There should have been a backup nut to lock it in place. Depending on the wall material there also should be an additional nut and washer to prevent the toilet from crushing the wall material. Do you have a picture?
