What is UTC Ultra Thread 140 Denier?
UTC Ultra Thread 140 Denier is a lightly waxed thread that can be flattened completely while tying. This produces smooth, even wraps and strong fly bodies without creating unnecessary bulk.
Like all Ultra Thread products, it is not bonded and can easily be split for split-thread dubbing. Its greater breaking strength makes it an excellent choice for medium to large flies and for securing tougher materials such as deer hair, feathers, and synthetic fibres.
Ideal For
- Dry flies
- Nymphs
- Wet flies
- Medium-sized streamers
- Split-thread dubbing
- Working with deer hair and bulkier materials

It offers significantly more strength than the 70 Denier version while retaining the flat profile and the ability to perform split-thread dubbing. |
