I had the same thing happen to me and I just took another nut off and went to the hardware store and matched it to an equivalent flanged nut. 4 years later and no problem.

It it's a 14 mm wrench, it's a M10x.1.25 thread; if it's a 12 mm wrench, it's a M8x1.25 thread; and if it's a 10 mm wrench, it's a M6x1.00 thread. As mentioned above any hardware store will have nuts/bolts of these thread patterns for sale...

i think its Lexus Flange Nut #90178-A0024 | parts.lexus.com - https://parts.belllexusnorthscottsdale.com/products/product/flange-nut-90178a0024

The OEM part number for the Lexus GX460 engine cooling fan clutch nut is 90178-A0024. This is the standard flanged flange nut used by Toyota/Lexus to secure components along the cooling fan and pulley configuration for the 4.6L V8 engine.

You all are awesome, thank you.

I lost one nut holding on the fan clutch after a radiator replacement. Can’t seem to find a part # for the nuts. Does anyone have a detailed schematic that identifies them?
