hello I'd say the thing to use is the easi-out insert type where you drill a smaller hole into the stud and then try screwing one of these tools into it which have a LH / reverse threadhowever before doing this I'd say to use one of the freeze sprays that also contain penertrating oil like this http://www.halfords.com/motoring/paints-body-repair/rust-removal-treatment/halfords-shock-unlock-spray-400ml http://www.amazon.co.uk/TRIXES-Piece-Damaged-Extractor-Remover/dp/B007RMUCSY/ref=sr_1_3?ie=UTF8&qid=1451295529&sr=8-3&keywords=easy+out+tool and failing that you will have to drill it out carefully and then re-tap the thread , the issue with this is its all too easy to damage the thread but in which case you can tap it oversize and fit a thread insert like a 'helicoil' http://www.banggood.com/25-Piece-Helicoil-Thread-Repair-Recoil-Insert-Kit-M6-x-10-x-80mm-p-930993.html?currency=GBP&createTmp=1&utm_source=google&utm_medium=shopping&utm_content=saul&utm_campaign=electronic-xiao-uk&gclid=CIr2ituh_skCFYu4Gwodl2sIwg
