Rear mech hanger
I need your lights please!
Yesterday i realize that i lost the screw of the rear hanger (that who secures the hanger in the frame). The hanger is like this: https://www.paligap.cc/MEKK-Gear-Hanger-No-05-(AL-MODELS)_8501_p and the screw+nut look like these: http://soshanger.com/Nut-and-Bolt-for-derailleur-hanger-and-frame-attach.... The problem is i have found many like this but i don't know if all are the same and what exactly to ask. I contacted with the wiggle who i bought it, but they can help me.
Thanks in advance.

That happened to my Rose, Rose were more than happy to sell me a new hanger plus fittings - but weren't able to confirm what sort of machine screw it was (at least on both of my bikes the rear hangers are fitted with "M" screws).
I popped into my LBS and the workshop had hundreds of spare lying around, I did a quick comparison against the remaining screw and they gave me an appropriate screw. I had looked around online, but it's fairly hard to buy them in small quantities from my limited experience - certainly a problem if you aren't sure exactly what sort you need. Likewise B&Q didn't have the right ones available either.
As I understand it there are three dimensions to machine screws; width, length and thread spacing (whatever the correct term for this is), so it's fairly easy to buy the wrong thing.
I'm sorry I don't know. Again my advice is to give your LBS a call or drop in, this is the sort of knowledge which they'll know straight away and probably stock too.
I have a feedback from wiggle that says "you can use a standard chainring bolt" but what size (length)? i saw 5mm, 8mm, 13mm chainring bolts.
I don't know, BUT I'd imagine that these are all of a standard. For a quid I think you can risk it.
However it'll be quicker and nicer to nip down to your LBS or bike mechanic who will have these knocking about.
