Wheel hub hardware? (Page 1/1)

Guys... ugh... I stripped the head on one two of the wheel hub bolts I tried to get off. These are the bolts that hold the wheel hub to the steering knuckle.

Anyone know where I can buy a new set of these bolts? They don't seem to be available... neither Rock Auto or Fiero Store have them?


Thanks!

I believe is not only "odd size" but Class 10.9 or higher hardness that very few carries.
You can't use standard bolts etc to replace most bolts in suspension.

Not sure if the parts book has a part # for these, if so might show the size & material. You can check clipsandfasteners.com, dorman products, bolt depot.

This is crazy... I've looked everywhere, I cannot seem to find a single place that even lists them, let alone "available."

Worse yet, I'm seeing everywhere that these are only supposed to be single-use. So that's definitely a concern then...

I'm going to keep looking, but I'm not finding ANYTHING...

Ok, I took the best bolt I could find from the hub I removed, and took some measurements with my caliper, and also my thread chaser / sizing tools. I can confirm the following:


Thread size / width: M12 / 1.75
Head Size: 18mm
Property Class: Says 9.8
Bolt Length: 1.5" / 38mm
Washer Size: 24mm


I'mma going to see if I can find some bolts that are this size...

EDIT: Ok... I looked high and low... and found these on Amazon: https://www.amazon.com/U-Tu...ellow/dp/B07JGHYTDR/

They have all the same specifications as I listed above (from the originals), but they are 40mm in length, and have the washer integrated into the head. I went to look at the steering knuckle, and there is PLENTY of room for a longer bolt. The originals that are on there, are only 38mm, and there's probably 4mm of additional length before it even reaches the hole on the other side, so these will actually provide a bit more gripping strength.

They say 10.9 on the head, which I assume is better than 9.8.

Comes in packs of 5, and I ordered three sets... (so that I'd have a good set when I redo the hubs on my own Fiero).

They will not have it with the torx head, but will have them in an allen head.
