Thread problems

apologies maybe a little OT but i've searched and not really found a solution.

Basically when i screw in my derailleur hanger bolt, it starts to go in fine and then just stops. The threads all look fine so is it a case of giving it a clean and some grease?

If you hadn't cleaned it and greased it already, you should have done.

Thread fail on so many levels...

You obviously need to buy a Thorn M8 fine grub screw for eccentric bottom bracket.

It's a fine M10 thread, the same as a Shimano rear axle.

I post threads just to see what products I'm recommended.

dont listen to these people,you need a spag-bolt with a offset eccentric thread made of titanium/cast iron alloy.if this dont work just do what we all do in times of desparation hit it with a big lump hammer

sounds like a crossed thread on either bolt or frame

mmm, any lbs should be able to re tap the threads.

cheers, rive gauche and velo libre. although the reponses have been funny for my now obviously stupid question

Sheldon Brown used to use an old axle with slots cut in it as a makeshift tap.
