Maybe I’m just being a little ‘blonde‘ here as I search but I cannot for the life of me find rivnuts in M12 and M10 with the correct thread pitch.

Just to confirm, the M10 bolts found on our Toyota’s are typically M10x1.25 and the M12’s are M12x1.50.

The only rivnuts I can find are M10x1.50 and M12x1.75. I hope I’m just being dumb and this is not really as difficult as it seems ?

Thanks for the help !!

Don’t see what the thread pitch is on those. River nuts that I found that specified thread pitch were not the same as requested by OP.

for the OP, it looks to me like both the M10 and M12 have a pitch of 1.25. This table is a bolt torque spec table from one of my FSMs. The typical rivet nut sizes do seem to be M10x1.5 and M12x1.75

Yes, the M10 is a 1.25 pitch, which I guess is not common in riv nuts, and the M12 is 1.5, according to my measurements and my metric tap and die set, which is also not common in riv nuts.

I guess maybe I’m not loosing my mind ?

I'm not trying to be argumentative as I agree with your original premise--JIS rivet nuts are not readily available in the US. I even tried some japanese sites, but I guess those companies are also making for european and US markets.

I do have some 12mm used bolts & nuts as well as one new stud in my fastener box labeled "TLC". Mine seem to measure as M12x1.25mm. My point being maybe there are different pitch sizes used on the land cruiser depending upon application.

Not argumentative at all; I guess I never thought that maybe some of the M12’s are 1.25 pitch since my stash are definitely 1.5’s. Actually, come to think of it, I didn’t measure all the bolts so maybe I have a mix ?

My simple solution if the riv nuts I’m looking for are not avail is to buy M10 and M12 bolts that work with the std riv nuts I’m finding.

Thanks !
