No downward spiraling to the threads? Stacks of raised rings?"nut type grooves"?![]()
Yes I meant to say threads. Yes they are left handed threads."Nut type grooves"? Do you mean threads. If so, are they left hand?
I did a google after KnurledNut said what it was, and I found ones just like it. I have a Craftsman Set but it doesn't look like that.Removal tool then... very popular even today. I wonder when that is from.
Yea... the modern "extractors" that I have... have a much more angled thread. Providing a bite with a bit of hammering before twisting off. YOURS however look like it was meant to simply left twist it on. Very interesting design. Thanks for sharing.I did a google after KnurledNut said what it was, and I found ones just like it.
