Extracting stuck screw

I was tightening the screws on my sda srs 1.2tl passive radiator and the hexagonal bit actually broke off in the screw. Now I have no way to unscrew this particular screw.

What would be a safe way to remove this screw? One those those Grabit screw extractor kits?


Thanks....

    Gotta say - I use screw extractors to extract screws; they work well! :-)
    I've had to extract broken fittings from things far pricier than most loudspeakers (typically, broken fittings in HPLC pump heads in the lab).

    Thanks, Mark - say, do you still use those old Polk towers you picked up from me about 4 or 5 years ago? I can't even remember the model number, but they are what brought me here!

    They are Monitor Series Model 9As. To say I use them would be an overstatement, but they are a proud part of the collection :-)

    The 9A, to my ears, is a pretty decent sounding loudspeaker - the original Model 9 had a pretty bad reputation... but that may have been largely due to the use of Motorola "orange juicer" piezoelectric tweeters.

    Back on topic, if the screw head is still there, with a torx/hex bit stuck in it, you could grab the head of the screw with some needlenose vise-grips or, grind a slot in it with a dremel tool to use a straight screw driver in. Pics?

    Not a bad idea. I tried using an awl and a hammer to 'unstick' the torx bit that is stuck in the screw but I wasn't getting anywhere. I do have an (unused) set of those grabit things my inlaws got me a few Christmases ago - I may give it a whirl. I will take a pic as soon as I get the opportunity.

    What I am mostly terrified of is accidentally punching a hole in the butyl surrounds due to a ham handed mistake :)

    No problem; they were an oddity I picked up on Craigslist a few years ago and ended up giving them away to someone more deserving than myself. From what I understand one of Polk's first models?

    the screw extractors I used need a couple surfaces to bite on and the bit is very hard (cant drill) so and that wont work , the previous post using a dremil with the thin abrasive disc to cut a slot is the best plan .
    my guess is that if it broke off a screw bit its gonna be very difficult .
