Stripped T-30 Bolt

[stirtloe]

I have been trying to remove the rear carrier section. One of the T-30 Torx bolts is stuck and has become stripped (see photo). I have tried a screw extractor but it doesn't bite (maybe a £7:50 set from Amazon is not of the quality required).

My next course of action is to douse liberally with Plus Gas and use a Dremel to cut a groove in it capable of taking a wide flat bed screw driver. I have seen in other threads that using a heat gun beforehand is an option but I am loathe to use one given the surrounding plastic.

Any suggestions/tips gratefully received.

Try holding a soldering iron (switched on, of course) on the stripped torx recess on the bolt head for a few minutes. Then hammer in an oversize torx bit and use an impact driver.

DAMHIK …

If you can get hold of a narrow chisel, you could try a good whack on one edge.. The shock and force should help.

When you say stripped you mean you’ve fucked the head up don’t you?

I wouldn’t put heat on it because I’d be worried about damage to the plastic because you just know they’ll have used the BMW equivalent of threadlock on it and unfortunately that’s going to need about 400c to destroy the thread locking compound. Do as you’ve suggested, cut a slot in it and use a good fitting flat screwdriver with a set of vice grips round the shaft as close to the screw as you can get them.

Or, after cutting the slot use an impact driver and a feckin big hammer to shock the bolt into movement.

These are the tools you need for extracting screws and bolts. You drill a hole down the bolt and then hammer the correct size extractor in. They're not cheap but worth their weight in gold. As an aircraft engineer I've used them thousands of times, and that's not an exaggeration.

There’s a common theme - you need a hammer.

Can I get an amen?

I have an impact driver, a small cold chisel and a hammer

Resistance is futile

@ Stirtloe - Seems like a quick ride up the M40 to Worcester is in order, armed with a bag of doughnuts and a coffee. I'm betting that applying Worcester aviation tools beats using a 'Birmingham Screwdriver' every time....(and I'm a Brummie by birth!)

Amen to that, brother.

I know you are all waiting with bated breath for the result. Repeated goes with the extractors didn't work.

The chisel and hammer worked by shearing off the head enabling me to get the cover off. I can rotate the sheared bolt and unscrew it.

Thank you for the advice

You would be very welcome especially with a bag of doughnuts!
