UTC Ultra Thread is a premium nylon fly-tying thread that combines exceptional strength with a slim profile, making it a favorite among tyers worldwide. Its smooth, multifilament construction lays flat on the hook shank, reducing bulk and creating clean, elegant bodies. Perfect for everything from tiny midges to large streamers, Ultra Thread provides excellent grip and durability for patterns that hold up cast after cast.

Available in 70, 140, and 210 denier, this thread gives tyers the flexibility to match hook size and fly style with the ideal diameter. The round, non-bonded design makes it the go-to choice for split-thread techniques, dubbing loops, and precise material control. With a huge range of colors, Ultra Thread allows endless customization whether you’re tying subtle classics or flashy attractors.

Recommended Uses:
– 70D: size #14 and smaller flies (similar to Danville 6/0)
– 140D: sizes #6–14 flies (similar to Danville Flymaster+ 140)
– 210D: ideal for streamers, saltwater, and big predator flies

Ultra thread olive

My go to thread. Great value and product. Olive color is great for most fly tying.

Great thread for specific flies

I use the Ultra 140D thread for tying buggers, smaller Clouser Minnows and balanced leeches and it works great. They have a great assortment of color choices for my flies.

Solid Thread

I use this thread for a variety of flies and it does not disappoint. Recently purchased some 140 to tie up some hoppers and it is strong and consistent. Good all around choice for a variety of flies in different strengths/diameter.
