    Also think why it rounded. Was it due to screw being seized on its thread? If yes or maybe help it out with heat and lube alternately a few times to get the lube to penetrate and give the chosen tool method a better chance. As the hub is ally then I would say definitely heat will help. Warm it till your spit dances off. You will need beer to maintain spit level. Best of luck.
    Greatest discombobulations to all my readers.

    Too much locking compound I think, and being ham-fisted with the Allen key.

    Will they work on Allen heads?

    They are meant for normal bolt heads, but some of the bolts I have removed with them were round.

    So I cant see why they wouldn't work on an Allan bolt
    Quite old now, But here to learn more !

    Also depends on bolt quality. I got so much purchase on motorbike fork stuff last year (seized in to alloy) the heads simply sheared off.

    As above heat and wd40 first. Seems to free up most bolts I find.

    Could try some of that cold spray to contract the bolt a bit, such as " freeze your nuts off " worked for me it the past.

    Bu I'm too am currently failing on a bike project.

    Getting out the big flat headed allen socket bolts that connect the subframe to the main frame. GSXR . Internal allen sockets rounded off prevoiously.

    try tightening it once to break the bond. if that fails, get a left handed drill bit and drill down the middle of it, odds are it'll come out while drilling.

    If it is thread-locker then definitely apply heat - have to do it all the time at work. It will soften the compound and as a bonus will expand the aluminium slightly.

    As suggested previously, bash in a tight fitting torx or splined bit and then add some tack welds to secure it. Put gaffer tape on the alloy to protect it. Undo the bolt while the welding heat is still there.

    Those bolt removers work a treat on round Hex Heads... you need 'em when working on Mercedes engines...

    I also use the Acetate / ATF fluid mix too... evil stuff- so don't swallow it... but really works on anything seized
