UTC Ultra Thread 70 Denier gives fly tyers the control needed for precision trout patterns, from slim-bodied nymphs to delicate dry flies. This flat, smooth, lightly waxed nylon thread lays evenly on hooks from size 14 down to 32, preventing bulk buildup when dividing wings or shaping heads. With a breaking strength of roughly one pound, it’s strong enough for durable flies yet fine enough for small midges and emergers, making it a favorite choice for tying trout flies that fool selective browns, rainbows, and brook trout. Each spool carries 100 yards, offering plenty of thread for seasons of tying.

  • Flat, smooth, lightly waxed nylon thread
  • Slow building thread prevents bulky fly bodies and heads
  • Ideal for trout nymphs and dry flies in hook sizes 14-32
  • Breaking strength of about one pound
  • Has a breaking strength of approximately 1 lbs.

Made in the USA

    Ultra Thread Review

    Posted by flys by day on June 12, 2019

    I am new to fly tying, but I really like using the Ultra thread for tying my flys. It goes on smooth and makes tying a snap.

    One of the Best

    Posted by BillTFlyfish on June 12, 2019

    UTC 70 is good for about 90% of the flies I tie. Good strength. No surprises.

    My Favorite Thread

    Posted by Goose on June 12, 2019

    I like the thread because it lays flat and I can easily split it to apply dubbing.

    I tie small Flies, and naturals with this product, and teach fly tying classes. My students use a number of different threads, but they always ask about where they can get the UTC Ultra 70.
