frame fitting thread sizes.

[dg01]

Hi all,

Just about to rattle can spray a Raleigh frame. I was going to simply thread some set screw into the mudguard threaded holes. Does anyone have any idea what thread size they are?

Rear derailleur is M10 x 1, I have a couple of bottle cage set screws I can use for bottle cage mounts, and I'll simply mask out the BB. I will chase the BB afterward anyhow, to be on the safe side, but just wanted to be able to thread screws into the mudguard mounting threads to protect them.

Thanks,
D.

M5, same as the bottle cage threads.

Re:

Unless it is a an old frame, say before 1980, the mudguard threads may not be metric but a British thread, 2BA.

Bottle cage bolts worked a treat - thanks all!!
