I'm, unfortunately, in a place where I need a stud extractor. It's an 8mm thread sticking up about 3/8ths of an inch, so solid territory for an extractor, but not where vice grips will help. I'm not a tech, so, no snap on, etc. What's your go to? (FWIW, I've borrowed the snap on ones)
Still trying to find a good clamping stud extractor
I have this Craftsman. Works great on MC engine studs. May not work in your case.

I've tried the clamp style and the eccentric style. I keep coming back to a pair of nuts jammed together or vice grips and a bit of heat.
Of the "proper tool" types I've used, the collet style have been the best.

I used to have one. Didn't have the best luck
In reply to ShawnG :
What brand? This is a broken bolt so not enough threads for the double nut
Put a nut down onto the stub and nuke it in place with a welder. Let it cool slowly back to room temperature whilst dousing it with penetrant. Use appropraite sized tool to unscrew the nut.

Snap-On but there are comparable ones on the Bezos site.

Maybe the nuclear route is the best. I usually like to use a tool but it would provide the necessary heat and save money for now.
For general stud installation and removal I really like the GearWrench stud sockets:

I doubt they'll work if the "stud" is just a bolt that you broke the head off because it's stuck, though.

I was curious about that set. The concept seems very similar to the snap on tool
