UNI-Thread 6/0 Waxed



Crafted by UNI-Products, this 6/0 continuous polyester filament thread sets the standard with its 136 denier and a breaking threshold of 33 oz, ensuring durability without bulk.

Black Black Black

I used to tie custom flies for a living and have tried many threads over the years. UNI 6/0 is my go-to thread. You can't go wrong with black if you're getting started. Best of luck on your fly tying journey!

Best Fly Tying Thread

I've used 6/0 UNI-Thread for years and never had a single problem. It's a strong thread that holds down materials really well and you can put a good amount of pressure on the thread without worrying about a breakage. It's also really great for building up fly heads and bodies quickly. Plus, it holds whip finish knots very strongly.

Great All Around Thread!

I have been tying flies for the past 15 years and have not found a more versatile thread than the 6/0 by Uni. The colors are great and the thread works well for forming small heads. I use this thread for size 14 and larger hooks.
