I recently bought a toilet seat and the seat holder on one side loses over time making it loose from one side while another side is tight. I realised I was missing one these nht cover and hex Nut to fight it. I was wondering if the holder is loose because of the following

  1. Hex nut too tight it
  2. The displayed cover to cover the hex nut

I am new at this and wanted to find out about how do I determine the nut sizes? As the one I tried on the screw are too big or small. I am a layman at DIY so what is the best way to determine which nut goes on the screw? and if the attached image of the cover is needed or optional?

  • The nut could keep it from staying up if the seat won't stay properly leveled. You can usually buy just the nuts from a harware store. But if the nut isn't tight enough, the seat won't stay level, allowing the rear portion to drop to the ceramic rim, and allowing the cover to tip forward and close. – Jeff Cates Jun 12 '17 at 5:54

  • I presume it is a new toilet seat, that did not come with a parts diagram nor makers name? Otherwise it is just a hex nut with a fancy cover/tightening handle that makes it work like a wing nut. – Jack Jul 5 '17 at 3:37
  • @Jack Yes it is new, It came with part diagram but I think, I didn't see any second fancy covering, Every time the seat is open or closed (IMO), the hex nut that doesn't have the cover, drops a circle. – Nofel Jul 5 '17 at 8:53
  • If you mean drops a thread, as in comes loose without turning it, you may have a metric thread over a standard thread or vice versa. It should be 1/4" diameter, I do not know of any seats that come with metric nuts, that's why the manufactures' name can be important. Or the bolt or the nut could be stripped, but not likely. – Jack Jul 5 '17 at 14:49
