Zoro is resilient sure but Jack appears to be even more so, Mosshead wouldn't been able to surive a trunk wack from Zunisha or been able to fight Fujitora and Sengoku. Oda jerking him off by having Zoro overpower Jack would disrespect the efforts of Mink Tribe, epsecially when thye have actual beef with Jack when Zoro doesn't.

As for the whole nails thing I don't really care, but it just shows Zoro's body is as vunerbale to attacks as Sanji's body or Usopp's body. He's still a non-devil frut powered human being... guys calm down, Buggy took him out with a knife in the third arc he isn't made of steel. Zoro would've died from Mihawk's slash if he didn't recive medical attenion immediately afterwards.
