Have just bought a used Marin Mount Vision and both of the bottle cage bolts
have a problem in that the captive bolt inside the frame is turning.

Any one got a solution to this?

Chances are you have what are called Rivnuts. I had the same issue on
my Litespeed. Most good bike shops should be able to sort this for you.
Alternatively you could buy a 'rivnut' tool, or ask me to send a pdf
document I have on "pulling rivnuts without a rivnut tool".

If they are rivnuts then I know how to tighten it using a nut and bolt and a
spacer.

But I have the problem of how to get the screw thats in there out?
Do I then drill the rivnut and use a new one or can I tighten the existing
one?

Superglue?

unlikely; the torque exerted on even an (M2?) nut is enough to break the
superglue.

The scourge of Rivnuts.

Be very careful.

You can try drilling out the bolts, but you'll end up with bits of metal
inside the frame, and likely destroy the existing Rivnuts, which you'll
have to extract.

Consider a Klickfix
"http://www.xxcycle.com/cgi-bin/shop.pl?SCREEN=lp&CAT=26" or Zefal Gizmo
clamps.

I got the screw out on mine by heating it, and there was just enough flange
on the rivnut showing to apply a bit of force to keep it still while I
turned the bolt. But then it was a bare frame with no paint to damage...

Hiya gez...
A quick and dirty trick for the loose rivnut:

Get a capscrew(bolt), nut and washer of a size to fit your rivnut. Make sure the capscrew is long enough to thread fully into the rivnut with the nut and washer already on it.

Thread the nut onto the capscrew all the way and then put the washer on.

Now thread your "tool" into the rivnut......

While holding the capscrew steady, turn the nut down tight onto the rivnut. Don't overtighten but get it pretty tight.

Back off the nut, remove your "tool" and install your bottle cage.

A rivnut works like a rivet..... what you have just done is grabbed the part of the rivnut the expands by putting your capscrew in it and expanded it(more) by tightening the nut. Works pretty good.

Next question??

unlikely; the torque exerted on even an (M2?) nut is enough to break the
superglue.

The glue may only be necessary to told the screw untill the there is
sufficient pressure on it to prevent it from slipping.
A compressed super glued bond will be very strong indeed, it only
needs to stronger then the friction between the nut and the bolt which
is pretty negligible on a correctly fitting oiled nut.

Another solution is to use three nuts (if there is room and lock two
togeatther
so you can use them to stop the screw from turning whilst you tighten
up the third bolt.

You can also maybe use pliars to stop it turning or file the end
so you can hold it with pliars and not damage the thread

The superglue trick worked for me - but it was a brand new frame and bottle
cage bolt.
Applied superglue to rivnut, applied oil to bolt and gently undid bolt.
