Left-Hand NC & NF Rethreading Dies

  • All left-hand NC-USS dies are gold zinc-plated, and all left-hand NF-SAE dies are silver zinc–plated so you can quickly tell them apart
  • Rethreading dies will not crosscut or undercut the thread the way a cutting tap will
  • NOTE: These dies are not guaranteed when used on hardened threads or to cut new threads.
  • MADE IN USA
