Does anybody know the thread pitch for the Motor Mount Nuts on the 89+ Supra?

Rather than try to source out some, I can get them at my local bolt store. I need to bolt them up so I can take my car to get the exhaust welded.

If your talking about 4 symetrical holes on either side of block.They are 10 mm X 1.25 pitch about 30 - 35 mm long.Hope that helps?

actually, the ones that bolt the motor mount to the chassis, not the motor mount bracket.

as seen here on the BIC motor mounts:

I'm looking for the thread pitch for those nuts. Stock. 89+.

I need the size of the nuts. But wouldn't it be the same size as the studs? The nuts fit a 19mm socket, the ones you have to unbolt when you pull the engine

If you are shopping for the nuts at your local hardware store, the head sizes are probably going to be different from stock. JIS (Japanese industry standard) fasteners have smaller head sizes for a given thread size compared with metric (above m6 size).

I just ask them for a nut with a built in washer. it solves everything. I got nuts for my headers and they were the same head size (14mm) as the other one

IJ, I got some 12x1.25, they don't fit. guess I'll shoot for the 14x1.25 tomorrow.
