thermostat housing nut size

[wei]

Quick question. I was replacing the thermostat today and in the process of putting the housing back on...I dropped on of the nuts into the engine bay

Anyway, do any of you guys know the specs for that nut? I know it's 10mm on the outside, but is there any specifics on inside diameter or can I just go buy a 10mm nut?

Thanks.

You can get them from any Toyota dealership. Or if you can get the other nut off, I'd bet Home Depot/Lowes will have a matching nut with the same thread pattern.

Also, you should buy a telescoping magnet to help pick up small nuts/bolts.

Yeah I'm trying to avoid having to take the other nut off to match. I might just go to Lowes and grab one of every 10mm there is... can't be that many right? And they're probably cheap.
