More About UTC Fly Tying Thread

Ultra Thread from Wapsi, widely known as UTC, is a popular thread for fly tyers, valued for its consistent colors and the choice of breaking strengths it offers across patterns. UTC comes in both 70 and 140 denier, with the lighter weight suited to fine work and the heavier weight handling larger flies and more demanding wraps.

The UTC family of spooled products

  • UTC thread in a broad, dependable color range, including black, burnt orange, red and hopper yellow.
  • Ultra Wire for ribbing and weighting.
  • Ultra GSP for strength in fine diameters.
  • Ultra Tinsel for flash and accents.

Whatever the color or weight, UTC thread lays down smoothly and helps build clean, durable flies for the next fishing trip. Together the UTC spooled products make a reliable, versatile foundation for a wide variety of patterns. To pick the right UTC denier for a fly, see our guide to which thread size to use for which fly and our thread comparison guide.

What is the difference between 70 and 140 denier UTC?

70 denier is finer for delicate, low-bulk work, while 140 denier is stronger for larger flies and wraps that demand more tension.
