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
