UNI’s thin waxing process keeps the bobbin tube clean instead of building up over a session, on a strong, do-it-all 6/0 thread for dry flies through medium streamers.
Specifications
- Spool Length: 200 yards
- Denier: 136
- Breaking Strength: 33 oz
- Construction: Continuous polyester filament, rounded profile
- Finish: Waxed, with a thin coat that minimizes bobbin build-up
Best for: dry flies, nymphs, and small-to-medium streamers; a reasonable single-thread choice for a bench that only keeps one spool on hand.
Also available in 3/0 and 8/0 for patterns that need a heavier or finer thread.
The rounded profile sets it apart from flat-laying threads and gives a tyer a different feel at the vise, while the 33 oz breaking strength on 136 denier holds up to medium streamer strikes without adding bulk to smaller patterns. A 200-yard spool covers a working session without frequent respooling.
FAQ
Q: Does 6/0 hold up on anything bigger than a dry fly?
Within reason — the strength-to-size ratio handles medium streamer strikes, though it’s not built for the heaviest saltwater or big-game patterns a heavier denier would cover.
