Quick take
140 denier nylon fly tying thread with minimal twist for flat wrapping and precise fly construction.
UTC Ultra Thread in 140 denier black is a flat, lightly waxed nylon fly tying thread with 100 yards on each spool. It lies smooth on the hook for slim bodies with little bulk, which suits trout flies on hooks around size 6 to 14. Spinning the bobbin turns it into a rounder, stronger strand when a fly needs it.
Best for
- Tying small to medium flies
- Fly tiers who want flat thread for close hook-eye wrapping
- Freshwater and saltwater fly construction
Skip if
- You tie only large streamers or bass bugs
- You prefer thicker or more heavily twisted threads
Strengths
- Nylon stretches and grips materials better than polyester
- Flat construction wraps smoothly on small fly hooks
- Lightly waxed for better thread control
Trade-offs
- 140 denier is lighter than heavier threads
- Nylon is less commonly stocked than polyester alternatives
- Thin thread requires practice to prevent breakage
