dead allen bolt help

[motomagII]

i have a brsand new stem fitted to ride has got allen bolt fitting to forks .one is stuck tried once and the allen key rounded the head off straight away how the hell do i remove this now please

Get a torx or something similar, hammer it in & try to undo 

Or if no good drill it & try an easy out 

[lazychubs]

undo all the others then it should come undone a tad easier

[motomagII]

its the one that holds it on the forks .tightened and loosened the other one to see if it made any difference but didnt then the allen key moved and killed the shape of the allen part of the bolt .

whats a torx and easy out ??

[lazychubs]

cant you try and whack a slightly bigger allen key in
as ive done that b4
easy out is a reverse drill bit
as it drills in it winds the bolt out

Greg is it an 1 1/8th new school stem we are talking about here. If its a standard or an s+m you need an imperial allen key.

hi mate its a standard .probably used the wrong type and rounded it or summat if your going to bones you could have butchers for me ???bring ya tools lol
need to put another couple spacers on and cant at moment bars to low

Greg you deffo need an imperial allen key < if you use the right one you may still be able to undo it without to much bother 7/32th is the size I think but will check my tool box to be sure.

i had this prob once tried every allen key goin still no joy.. so tryed this.. take an allen key 2 sizes smaller, fill the hole in the bolt with nonails or some kind of hardener, put in the small al key leave for 2 -3 days untill rock hard, loads of wd round the bolt a it turned out first time

[lazychubs]

good idea on the nonails ya could also use araldite

[insideoutland]

any builder yards will have sumin for the job. if you go for the no nails go for the super pink. its only £2-4 per tube and plenty left to put up the missies shelfs

Imperial for sure.

Tighten the other bolt as much as possible.  Hammer in a torx fitting to the problem bolt as others have suggested and with a bit of luck you'll be able to wind it out.  The important bit is that the good bolt is as tight as fook.
