You never know what will work
This set to me is a cross between the strait and spiral extractors. It is straight but more angular and has 5 flutes vs 4. The 5 flute design also means you can use a normal socket and breaker bar if need to be get the fitting or screw out. I gave it 4 stars as the set needs to include the next size bigger. I ended up using a different tool to get my fitting out as the set didn’t go big enough.

Very well built
It didnât work for me, but these are very well made. Super stout. Strong, even after banging on them, barely a scratch. The edge are sharp, and strong. Guess my truck bed bolt was too stuck to back out.
