Need help with a bolt...

[CEgg11]

I am trying to find the bolt that connects the ball joint, strut and control arm for the 240z. I lost mine in a move, and can't find. Any help is appreciated.

10 x 1.25 maybe. Not sure about the special washer. I don't think that I have those on my 280Z.

If it's any help to you, the bolt size is 12mm and the thread pitch is 1.25mm.... Not sure about length though.

[Zed Head]

That actually sounds more reasonable. It has a 14mm head if I remember. Not sure why the partsmanual says 10.

Pretty sure it's a shoulder bolt though. The shoulder locates the T/C rod. I would just go to the dealer and ask. They have better parts files. Surprising how many of these old parts are still available.

30 mm is the length. 12x1.25 is correct. Grade 9. They are special Nissan bolts with a shoulder that fits the steering knuckle tightly.

Curtis, I should be home on Saturday if you want to come over. We could take a look at my 240Z, and you could get all of the dimensions that way.

Class 10.9 not Grade 9.

I apologise for my careless use of grade information. The head of the stock bolt has a "9" on it. I believe this is equivalent to ISO grade 10.9 as John mentions. Look for this designation on the bolt head if you go to buy a metric bolt from a supplier. These are important bolts, don't skimp on the quality.
