Heat induction tools are fantastic for this but are not cheap at all averaging around 3-400 quid most will find as daddy suggested, a direct heat source is your likely tool of choice
A carefully applied heat source will help, as will a stud extractor, which will require you to also carefully drill into the centre of the stud section remaining and then fit the SE, which when added to use of heat, will in all probability get this damn stud issue sorted for you, an incredibly common one I hasten to add. It's not that clear from the photo, but if there is some thread still present, you might be able to fit two nuts onto this and work the upper one against the lower one with a spanner, again after having gently applied heat to the area, which could be worth having a go with. If there isn't enough thread left, then back to option one above. There have been numerous problems exactly like this asked about before on this forum, so if you try a search, no doubt you will get some more assistance here. Take your time and with a bit of luck you will get there! Regards TonyN
Thanks. I managed to sort it by cutting it flush with head and drilled it out plus re threaded it to take a new stud.
