Cabriolet Mechanism, need a screw

One of the screws joining my top mechanism broke. See attached. Having a hard time finding a replacement. Checked with Ricambi and they can't find the part listed by Ferrari.

Anyone here had to replace one before and can recommend where to search? Much appreciated.

I've got tons of Mondial bolts and screws, do you have a pic of what it should look like?

Looks like a flat head cap screw to me? Does it have a shoulder?
Have a look at McMasterCarr.com
They should have what you need.
If I had my car here I would take my screw out to identify it for you.

Thanks everyone. Here's what it looks like.

That’s going to be a pain to find. Not a common piece of hardware for sure. Easy enough to make if you need to.

Won't get an exact one but McMaster has tons of binding bolts

If you measure it up I will knock you one up in a few minutes, I assume it is threaded internally .

 

- And this folks is why I love Ferrari Chat Mondial Section!
What a generous offer.

A little hardware trivia.... What are binding bolts also known as?

A drawing with sizes and the internal thread would help ( I am assuming it has an internal thread from the picture)

 

I will do this! Thanks Mike

 

Let me know if you guys have any suggestions? Maybe there are some available already?

I noticed these, but not sure exactly which one to get?

All these sizes are fine but what pitch is the thread ? Normal metric or metric fine ? Try an 8 mm bolt in the thread( I am assuming m8 from your pics) m8x 1.25 is the normal or it might be m8x1.
Once you have the correct bolt to fit the thread, get a piece of white paper then put some dirty oil from you car dipstick on the threads- press the threads onto the paper and it will leave the imprint of the thread peaks. Count the number of peaks over the greatest distance possible say 10 or 20mms and work out the pitch. 8 over 10mms is 1.25. and 10 over 10mms is 1

 

super appreciate the advise, I will do this and report back to all of you!

 

Update...turns out Ferrari at one point made a full kit of every screw in the cabriolet top mechanism because they we're failing. It wasn't cheap but I was able to buy one of the kits. I don't need it all so if others need pieces message me and I can likely help.

 

How did u get on

 

Thanks Mike32 for following up, I was going to home depot and find something, but an Fchat member was gracious enough to offer to sell me 2 of the originals, so just going to follow that route. Before I install though, I will provide more pictures for posterity just in case somebody wants to buy some from a local hardware shop. I think you can find something very close that will work exactly the same.

Stay tuned!

 

When u get sorted, put up the thread size. as I might knock a couple up in stainless as an exercise, only 10 minute job

 

Mike32, I am in need of six of them, if and when you make some up. I will be interested in purchasing them. Thank You Dominick

 

I await the thread size in order to make some up, any idea what it is ?

 

I will try and take one apart in the next day or so. Dominick
