Damaged fastener removal service

[whitelion65]

Hi folks,
Is anyone aware of a stripped screw/bolt removal service in Orange, NSW.

I HAVE A 2mm Allan grub screw in a sewing machine that has been munted.

I’ve tried jamming a torx driver in, and an easy out. The screw is only 4mm long, so getting purchase is difficult.
The other screw on the shaft was severely overtightened, but I was able to get it out in one piece using Allan key and scanner.

I have used penetrating oil and freeze spray on the damaged one , without luck.

Cheers
Steve

No; but what about:

Or drill it out with a reverse (left hand) drill bit (e.g. https://www.amazon.com.au/YUENTOEN-E...s%2C301&sr=8-6) and replace it perhaps.

"Scanner"; how was that used?

Thanks,

This is a case of a knucklehead butchering something.

Has anyone had experience with Kingchrome quick-outs?
Maybe on a pedestal drill, they could do the job?

I work on a lot of old shitty cars, and use these things:

Never failed yet.

Not sure they go down to 2mm.

Kingchrome quick-outs

Kincrome perhaps.

Aldi have similar items on special buys at the moment too. Same as these: https://www.aldi.co.uk/workzone-dama...96188205481300

This type usually works well on grub screws:

2mm - if that’s the major diameter - is so small, I’d think you need to make a drilling jig. Hole is blind?

Depending on how munted, munted actually is,
a 3/32" imperial hex key is a little larger then metric 2mm
forced in, it might be enough...

I have the shaft out, so have access to the screw. I’ll post a pic…if my acquired brain injury will allow!
I get the feeling that experience counts in a situation like this…hence my cry for help.

Is the shaft able to be set up in a lathe, a good machinist should be able to do something with it, perhaps using the left handed drills mentioned previously.

A gentle bit of heating may help if possible.

Heating it gently can also help loosen things up.

After heat and freeze spray, the easy out I used chewed the grub screw out, tith the bottom of it holding fast.

The fitting has been ground off and replaced.

I’m sure a machinist could have drilled it out, re-tapped and installed a larger grub screw. But at what cost? And the danger of damaging the shaft.
