I have just got a fifth 500 Abarth alloy for a spare but the bolt that held in the stock spare is too short because I want this wheel to face the other way up:




I think the best way to get round this is by getting a longer bolt but it will need to be the same diameter to fit in the existing hole
Does anyone have an idea of what the diameter of the bolt is or have a calliper to measure it?
Or if there are any other ways of securing it down?

Any help would be brill
Cheers!

Not got an answer for your questions but aren't the 500s 4x98 so will need wobble bolts to fit?

Since he already has these wheels fitted I suspect he's figured that out already I don't know the thread off the top of my head but I *think* it's M10 with a 1.5 pitch.

Oh haha, thought you just bought one as a spare. I'll just leave quietly...

Haha:') got a full set on and just fancied a spare that'll fit with the setup, cheers anyways!

take the bolt into a local fixings place and they will know the thread and sell you a new bolt

I found some cheap bolts that are m10 with 1.5 pitch on eBay just to test the thread dimensions but if they don't fit that sounds like a good plan B, cheers

The new bolts didn't fit, they're slightly wider than the stock bolt now on the hunt for someone that can measure what size bolt I'll need

Just buy a caliper and thread pitch gauge, you'll have them both for under a tenner

Must be an m8. I put a longer bolt in mine when I fitted a spare and used a standard metric caphead bolt I had laying around.

Got the measuring tools and the measurements I got are:

Thread: 20 G 1/4"

Bolt diameter: 8mm

Might be useful for someone else if I measured correctly

That's not right, you can't have a mix of metric and imperial measurements.

It'll be an m8 with a standard 1.25mm pitch.

Cheers for letting me know, is it definitely m8 with 1.25mm pitch or should I get a cheap bolt at that size to make sure?
Thanks

Finally in and secured with a long thread, butterfly bolt and the lid of an aftershave tin that was the perfect size
