Ah, I didn't see that, keep your fingers crossed. I was frightened by the power of these things, I dropped one in my yard which is ornamental pea gravel, when I picked it up it was encrusted by gravel. I never knew there was so much iron in various different stones.One of the blokes at work is bringing in a Neodymium magnet tomorrow
He could order decent keys at the same timeMmmm, may not be strong enough! Worth a try, then maybe order an earth magnet from Amazon, you could have it delivered to tomorrow, the you’ll have it when the rest of the hex keys snap...
If the key has cammed against slightly deformed flanks in the socket I fear for the magnet method. Trying to back it off the cam will be a lesson in extreme patience and tools smaller than you or I have to immediate hand, you may find that the tip of a pin looks very big when you try to probe for a gap to lever within.the broken off key is a couple of degrees clockwise of the female head (therefore jammed)

Its frustrating that people you would be happy to help (he rides bikes and posts here) aren't a short drive away. A friend laboured over a frozen seat post last year and did not ask me. Was a steel frame, he tried everything YouTube had to offer and failed miserably, eventually he asked if I had any ideas.Probably the only method that will get it out
It's not the cable clamp bolt which is damaged. The Shimano 105 clamps the cable to a rotating clamp which can then be adjusted with another screw which pushes the rotator around to tension the cable. It's that screw which has the problem.You could leave it until its time to adjust the cable then cut the cable and find someone with a bench drill and drill vice then attempt to drill the head and turn a ST screw in and yank out. It might be worth trying some taps on the back face of the thing first, if the socket is clean it might spit the key out.
I know, it took me a while and a proper read through to realise, that the key was only 2mm should have been enough information. I assume you will get to try your friends magnet later today.It's not the cable clamp bolt which is damaged.

It's still possible to get the tension right without using the screw simply by pulling the cable tight and then clamping. I'd have to have a few goes to get it right but at the moment (as luck would have it), the tension is bang on correct.
Got it now.I know, it took me a while and a proper read through to realise, that the key was only 2mm should have been enough information. I assume you will get to try your friends magnet later today.
