Bolt & Nut Sizes

[wrxn240]

Is there somewhere on the interenet where i can find sizes of bolts and nuts for various parts for the 240sx. For example, I'm looking for the size of the dohc header nuts...

Download the FSM (factory service manual). The header nuts are 14mm.

I think they're M10x1.25mm.

I posted this not long ago but no one seems able to search anymore. Wait, they never could.

8mm head - M5x.8
10mm head - M6x1.0
12mm head - M8x1.25
14mm head - M10x1.25
17mm head - M12x1.25
19mm head - M14x1.25 (S14 front spindle bolts)

KA bellhousing bolts are M10x1.5
The EGR and AIV are M24x1.5

That's the typical sizes for 90% of the bolts on any Nissan.

Oh yea, it's a 1.25mm thread pitch. I think 1.5mm is the DIS fine pitch thread, where JIS goes to a 1.25mm.

Sorry, didn't know you needed the thread pitch size.
