Cinquecento Sporting alloy wheel bolts

[Amateb8]

Okay, a bit of a long shot but does anyone have the alloy wheel bolts for the standard Cinquecento alloy wheels?

I've got a set in the garage I will have a look and see if I can find them 2mo

ANGELO you have not got a Cinque why would you want the wheel bolts 

[Eklipze3k]

Good question Rusty, the Cinq and 126 have different thread pitches ...

[Amateb8]

I inadvertently won a set of 13 inch Cinquecento Sporting alloys cheaply from ebay. I thought it would not be a complete waste having won it as I could install the alloys on my red Bis. It should fit right? I've seen it in other 126 Bis. I think Kitten75 has one installed on hers. Unfortunately, the set did not come with the bolts.

You must have been inadvertently shopping in your sleep 
Because if you had got the bolts and inadvertently fitted the wheels to your car you would now be inadvertently looking for new front hubs and rear stub axles as the wheel bolt threads would have been stripped

The specification of the Cinquecento Sporting alloy wheels + tires are:

PCD: 4x98
Rim: 13 inches
Tires: Pirelli p700 tyres on size 165 55 r13

Are you saying that the Cinquecento Sporting wheel bolts are not suitable for a 126 Bis?

[Amateb8]

I did a bit of research and found the measurements below. The Cinquecento wheel bolt specifications are identical to that of the 126. Is the ET the offset? Not sure what the length of the bolt should be though.

I think you're getting confused here - the Cinq wheel will fit the 126 no bother at all, but if you use the Cinq's bolts, the thread pitch of the bolt itself is wrong and will strip the threads of your hubs. 126 uses M12x1.5 and Cinq/Sei use M12x1.25.

s'true- I bought some lovely "fiat" chrome wheel bolts on ebay that where cinq pitch and learnt the hard way having to buy a new front hub....I learnt from my mistake so Y'all dont have to....

[Amateb8]

That was very helpful. I did not realise. You learn something everyday. Many, many thanks for the information. Sorry, a dumb question but what does these letters and numbers mean. Does the "M" signify the screw/bolt thickness? Where do I get the bolts M12x1.5. Do I need longer bolt length for the alloys?

[markymarc]

I had this problem when I got my BIS as the last person had done this on "1" wheel so when I got it checked over by a good mechanic he had to get it helicoiled as I couldn't get a hub at the time.  The guy had also used bolts for steel wheels and they only had a couple of turns so could've been a dodgey drive back!!
I think it may depend on the alloy wheel but do believe they should have longer bolts.  I got the right size but they were too long so fouled the brakes and had to be cut down......all 16!!

Hi Marc,
What thread length did you use?

[Eklipze3k]

Cinq/Sei Sporting alloys are basically the same, my Sei's bolts have a 30mm shank.
The M12 refers to the width of the shank (usually M12 have 19mm heads), the 1.25 refers to how steep/shallow the pitch of the thread is. Last time I got bolts I got them from ebay.

i have 126 bolts and run cinq alloys have done for quite a while and so far the wheels have not fell off.
