best way

[MT AUDIO]

to remove a screw where the head has snapped off,ive seen these extractor kits but not seen any that actually work without breaking 4 or 5 of them before hand.

any opinions on best used products?
its the bolt which holds the isofix bar in by the way

knock it round with a hammer and skinny punch, ive even managed to remove flywheel bolts this way.
those bolt extractor fings always break on me, never go on with em:dapprove:
