Tried to readjust the height of my coilovers on the front the other day. While trying to remove one of the bolts, the head broke off. I'm going to get the thread extracted soon. But can anybody tell me what part number this is or size of the bolt so that I can get one soon?

 

Take one of the others off on the other side, and take it to a good auto parts store, they should be able to match it.

 

I am. Just trying to see if anyone already knew it lol

 

Is it # 7 you are after?

 

Yea I believe so. Can u send the link pls?

 

Here ya go.

#7 is a lower control arm pin. I don't think it is the bolt in the OP

 

I went to the hardware store because AutoParts stores didn't have any. Only bolt I could get that was the same size had extended threading. I need to cut it to make it short enough. Gonna take it to a shop to remove the thread first before I can use the new one.

 

As long as the diameter, length and thread pitch are the same you should be good.
You can check the pitch with one of the other bolts by meshing them agains each other from opposite directions. Before putting it into the bolt hole so you don't risk cross threading.

There's no other parts shop or Nissan dealer nearby?
I'm thinking a lot of the hardware stores have bolts made from different material. Different hardness and tensile rating...and corrosion resistance.
Maybe I'm just paranoid...who said that?!?!

Anyway, maybe work on getting the proper replacement in the meantime.

 

Ohh duh, I was looking at the OP picture wrong. You're after the bolt that goes into that little black bracket that connects to the strut, not the control arm itself. I cant find a diagram of that anywhere.

 

Yea I tried looking for the diagram also but no dice

 

Pay attention to the bolt strength. Only use Grade 8 and above (SAE) or Grade 10.9 (Metric) for suspension parts. Otherwise you'll be snapping the heads off again. It will say on the bolt head.

 

It looks like a 9

 

This. Although for your bolt, its hardly load bearing at all so you could use a grade 5 without any problems in a pinch but 8 or higher would be hulk proof.

 

I believe this is what you are looking for, unfortunately it doesnt say the size.
