Re: Ask a Scientist

Can anybody tell me whether butterfly nuts stay on tighter/more reliable than normal nuts? Or is this just a strange idea of mine?

The toilet seat has normal nuts and they keep going loose and the only different factor to "the old days" I can see are those nuts. Does that sound logic?

I can't help you. Given the thread, are you looking for a toilet scientist?

No, I just misuse this thread to get some answers on daily, practical problems.
(I think I had my cable-twisting-problem question answered in here).
JagWaugh would always give me quick, clear answers and I'm looking for his successor.

Plus. what better way to flatter a useful answer from a guy but make him feel a scientist about it?

Thing is, although I have a hunch about those butterfly-nuts, it somehow doesn't seem logic that they hold tight longer.

Wingnuts (as we call them in the USA) are more easily tightened by hand, whereas traditional nuts need a wrench. I don't think they hold any better or worse though.

The butterfly nuts come with a plastic twister thing which makes it easier to remove and attach them. Its hard to find a good looking toilett seat that does not look like something out of an "old peoples home"

Re: Ask a Scientist

Yes I know they are easier to adjust but the thing is, the last seat that had them didn't need regular adjustment. That's what puzzles me.


And nope, I did not gain weight.

Don't worry. There seem to be some forum members with incredibly tight nuts. I'm sure they can help you.

Yes. But maybe you squirm around on the seat too much. That loosens the nuts!

Did you secure the previous ones with a wrench? If not and you only tightened by hand it makes sense why they would loosen more quickly. The wingnut allows you to tighten pretty well by hand.

Re: Ask a Scientist

You can buy locknuts (Kontermutter) which do not work loose and as said you need a spanner to tighten them properly.

THIS sounds good, thanks. Don't remember having heard of those. Thank you.

Re: Ask a Scientist

The short reply, as someone already mentioned, is "no, wingnuts do NOT hold pre-tension better than regular nuts". They are, after all, regular nuts with wings. If anything, they should do worse, as they are designed to be tighetened by hand, which means they get a lot less torque than when you use a spanner.

An option, as Marton mentioned, is to buy locknuts. They have an extra VERY TIGHT plastic thread set, that is nominally smaller than the regular steel thread. That means they are super tight. An option, if you can't find locknuts, is to add a spring washer (split washer, depending where you're from). They provide a bit extra tension when the fastener is a little bit lose.

Yeap. Spanner in the UK, I think, and wrench in the US (or vice-versa?).

There already is a spring washer.

I'll go to Hasler, they have everything and I can buy two pieces only there as well.
Thanks folks!

Yes, a wrench is a spanner. I didn't know that to begin with, that was part of the learning curve for me when I moved here.

Re: Ask a Scientist

I'll save you the joke of asking what happens on that toilet, or jokes about the diet, and suggest you double check the fastener itself if it keeps getting loose. Here's the reason: if you tightened with a tool (not by hand), and there's already a spring washer in place, only 1 of 2 things is going on:

- Option 1: there's something lubricating the washer/bolt interface (either it's oily for whatever reason, or the cleaning fluid used at home, etc). The bolt stays in place because the friction between the bolt head and the washer is higher than the tension applied on the thread. If something is lubricating that, then the bolt will tend to slip.
- Option 2: the base material is giving. You tighen the fastener, it "sinks" into the base material, and it becomes loose.

A wrench is American, a spanner is British. And why did you have to move to Switzerland to learn that?

Because here it is a "Schraubenschlüssel" (in Swiss-German a "Ängländer", a "clé plat" or a "chiave inglese".
As I never talked to someone who speaks romantsch only (amazing actually but I guess they wouldn't get very far in life if they spoke only that ) I don't know the name in romantsch.
