Al & Locktite

Is there any reason why I shouldn't use locktite on a bolt holding a
rear mudguard onto an aluminium frame?

Under no circumstances should you attempt this. Only today I heard of a
bloke who did and he found that it worked itself loose after only 80 miles !

I don't see why not, except other things might be better.....

How about using anti-shake washers, a nylock nut or cable tie, if any of
these are appropriate?

Thanks. Anti-shakes washers might do it, but not the others. It's a weird
attachment that I haven't seen before. The bolt goes through the mudguard
into a threaded hole in the angle of a Y-shaped rear fork, so when it came
loose, it rubbed the tyre.

you can't really see the offending joint.

None at all. You could also try a Nord-Lock anti-shake washer, or putting a
very thin nut on the inside of the dropout to lock the screw in place.

Another neat trick: remove rear wheel, insert screw from inside, secure on
outside with a nylock nut. If clearance is tight you can even countersink
slightly and use a countersunk screw.

Go ahead. Be sure to use mild-strength Loctite rather than super-strength in
case you ever want to get the rack off in the future.

242 or 243 is what you need.

No reason at all. In fact it is just the thing to use.

Make sure you use a grade appropriate to the size of the thread i.e. 242 or
243.
