How can i stop my toilet seat from becoming loose and moving?

Submitted by Hmmark1984 t3_znj730 in DIY

I've had an issue for a while now, where my toilet seat gets loose and starts to slide side to side after a little time.

Here are some images of the style of attachment the seat/toilet use, basically the black bit goes into the toilet, there's no nut on the underside as seems to be common, you then tighten the screw to make it grab as it pulls up the nut hidden in the black part.

The issue, I think, is that the part I've circled in red, is what the seat actually attaches too, and it's a separate piece to the part with the black insert and is only held in place by the same screw that goes into the black piece. It's meant to have some adjustability to account for different seats etc… however, no matter how tightly I do up the screw, after a few days to a week it will, I assume, work it's way loose enough to allow the grey disc/metal post to spin/move.

The only option I've been able to think of is doing something like using a thread locker on the screw/nut that goes into the toilet, but I'd like to avoid that, if at all possible, as it will make changing them very difficult if I ever need to do that in the future.

Either get a new seat or new hardware.

Do you have access to the bottom of the “part to be fastened”? I was thinking maybe you could use a nut and bolt instead of a screw and have a nut at the bottom of diagram 3.

Failing that you could try a rubber washer under the head of the screw, should absorb the movement from the seat.

I think I would get some silicone caulk, squeeze it into the hole in the porcelain around the rubber, tighten bolt, then let it set for 24 hours.

How would that solve the issue? The only hardware that works with the toilet, is the type shown, hence why it's being used, and the toilet seat isn't anything to do with the cause of the problem, and before you suggest it, no, I'm not getting a new toilet.

Try a wrap or 2 of thread tape on the screw.

Use a thread locking compound which is designed to be more easily removed. Like Loctite Blue 242.

Split washer/lock washer. That or Or lock tight. Probably not the permanent one. I believe that’s the blue one
