Carbonda mtb rear derailer bolt

[Casio20]

Unfortunately my bolt just lost it's internals during installation.

Can you please support to check whether it's mal12x1 or m12x1, 5

Do you may have ab Aliexpress link to purchase the bolt without the complete derailleur hanger.

Thanks a lot for your support

I believe that’s one of their Universal Derailleur Hangers so you can get any UDH hanger. Personally I like Wheels Manufacturing…I replaced all my Carbonda hangers with them after one seized up and snapped off while trying to remove and the other had to be removed with an Easy-Out because the hex interface stripped out.

Getting a UDH from Ali could work out if anyone has had good experiences with a specific company, but in general you’d be risking another one made of soft metal that might seize (less an issue if you grease it well first), or strip out.
