The Size 8/0 Uni-Thread is an ultra-fine fly-tying thread known for its strength, smoothness, and durability. With a denier of approximately 72, this thread is ideal for tying small to medium-sized flies, where precision and delicacy are essential. The slight waxed coating provides enhanced grip, allowing tiers better control over materials without adding bulk. Made from continuous polyester filaments, the Uni-Thread offers a balanced stretch, reducing breakage even with tight wraps. Available in various colors, it blends seamlessly into patterns while securing materials with a minimal footprint, making it a preferred choice for professional and dedicated fly tiers. Pre-waxed 200-yd spools.
