Rounded Hex Bolts
 

What are the different techniques I can use to remove a rounded hex headed bolt (made of something not dissimilar to swiss cheese)? :mad::mad:

I always find it helps if you headbutt a wall several times whilst screaming expletives at the top of your voice... usually followed by sulking and getting someone else to fix it :o

No help I'm afraid, but you have my sympathy ;)

Already gone through the self-harming and profanity stage, am now in the process of trying to be clever and make an even more serious mess, before I finally resign to taking it to someone who isn't a numpty! :mad:

Do you have good access to it?

If you could cut a small groove in the outer edge, you may be able to tap it with a screwdriver/chisel and (small) hammer to get it turning.

Dunno if that makes sense.

I've managed also to get a screwdriver (another bodge) that is like half a millimetre too big for the hex head... tap it in so it's snug and then try turning that... even better if you have a screwdriver with a spanner attachment thingy-me-bob

I'll try to think up a 3rd bodge, should all else fail.

Believe it or not, its the middle bolt on the top yoke of my 749 :( so access isn't great.

I'm thinking of drilling a small hole in it, and tapping a smaller hex socket into it? :puzzled:

try tapping a torx drive into the head of the bolt -it'll have to be a tight fit and then with luck the tapping and the grip of the driver when turned will loosen it----its worked for me in the past

Cool. I'll try that. Its this bolt:



What is the correct torque value for it?

Ooooooh, that doesn't look like a nice one to round off, you poor sod!
