Bolt extractor and max torque?

[vavavroom]

Is there a guideline how much torque screw extractors can take? For example, how much torque can a #4 screw extractor (9/32"-3/8") handle and how much more torque can a #5 (3/8" -5/8") take? Or how many degrees can you twist an extractor safely before it snaps? Thanks!

Nope

I guess it depends on the allow they’re made of...

I can tell you if they are carbide, they will snap without warning.
You won't feel it starting to give. It will feel solid , then a sudden snap.

I own this set. Paid $32 @Amazon, last one in stock. They’re pretty stout.

Carbon steel is all I know. Does anybody think a #4 can handle 25 ft-lbs?

$72 and out of stock at Amazon. Are they made out of Tiger Tank steel quenched in actual tiger blood? I have a set of Hanson-Irwin extractors that I've never had to use until now.

Don’t know, and don’t care. As I said, I paid $32, and that’s a good price (don’t get started on “just” prices, please)

 

[vavavroom]

I was interested in the reason for the product's superiority in comparison. I do care, even if you don't. I don't care about the price.

So you take the price as a measure of superiority? Whatever that means to you...I see you already started the “just” price nonsense.

Nope, thats more of a feel thing that you develop after you have broken a few extractors

I guess I'll go start breaking a few extractors. I'll be back in 30 minutes.

Don’t forget to tally the prices. We all might learn something from you

No, I do not. I made one crack about the price, you keep talking about prices. Stahlwille is makes top quality tools. They are not cheap. No problem. You said their screw extractors were stout. I don't doubt it. I just want to know based on what you assess their superiority. Did they work where others failed when you used them?

 

[vavavroom]

So a #4 snaps off without much effort. Maybe a stubby spline extractor is a better idea.

Actually, I never inferred superiority. I just plainly stated I got a good deal - to ME - on a quality tool. That’s all

Good deal is about price as much as a quality. I was just looking for a superior tool. Anyway, it looks like my screw type extractor won't do because it snapped as easily as a human thumb.

 

[AutoMechanic]

I’ve never broken any and put some good torque behind my Craftsman USA stuff.

If you're talking about the spiral corkscrew type, they usually break in the hole making the job twice as hard to do. The only ones I use now are Rennsteig https://www.homedepot.com/p/Rennste...tHmPPOvucBJjbyqI5ixoCTqQQAvD_BwE&gclsrc=aw.ds

I have this fluted set from napa.
