Fan clutch nut size

I need the nut size for the fan clutch on a 2003 6 cylinder Tacoma Pre-Runner. They fit a 12mm wrench. Do auto parts stores have these?

 

If it's oddball, probably not, if it's a normal 12mm nut, sure, also most decent hardware stores with a good nuts and bolts selection will have them also. Just get the correct grade and not some grade 1 quality crap.

 

You would go to any place they sell hardware, not auto parts.

It'll be metric, M10.

I'd get one in each thread pitch (so you'll buy 2 as there are 1 of 2 possible variants you'll need, 1.25 or 1.5). That easy.

 

^^^^^thats what I did

on T cover gasket replacement, everyone of the fan clutch bolts wee stripped out
I was lucky to get those suckers loose
Went to old school hardware store (ace in my area) $8 and I was good to go

 

M8 x 1.25 nuts

Hardware store more likely then auto parts but you never know.
