Semperfli Nano Silk Ultra 30D 18/0 Fly Tying Thread - Turquoise

Refined control for micro patterns

Semperfli Nano Silk Ultra 30D 18/0 in turquoise is engineered for precision tying on smaller hooks. The ultra-fine 30D construction pairs with 18/0 gauge to deliver delicate, consistent wraps that stay flat and neat from head to tail.

Despite its fine size, this thread offers impressive strength. It outperforms heavier 8/0 polyester in many tying applications while maintaining a diameter less than one-twentieth of that thread, helping you preserve taper and minimize bulk on fragile patterns. This makes it especially suitable for flies sized 16 through 32, where every detail counts.

What makes Nano Silk Ultra stand out

• Exceptionally strong for micro patterns, reducing the risk of loosened wraps
• Ultra-thin, flat wraps that resist buildup even after 100 turns
• Vivid turquoise color for visibility and precise thread placement
• Long 100-meter spool supports extended tying sessions without frequent re-spooling
• Consistent lay-down across bodies, wings, and heads for cleaner patterns

Real-world use cases

Use for micro patterns, including tiny caddis and mayfly imitations, where a fine thread preserves delicate profiles. Its smooth finish helps produce neat thread heads on small patterns, while the color aids in quick seam and rib placement under light conditions. You can also utilize it to secure fine ribbing or to wrap bodies with minimal bulking.

• Small flies from sizes 16 to 32, including micro and micro-body designs
• Delicate wings, tails, or ribbing that require precise, controlled wraps
• Head and thorax finishes where a flat, unobtrusive thread is desirable

Tips for best results

Maintain light, steady tension and keep the thread parallel to the shank. Wetting the thread lightly can reduce friction and improve lay-down on complex bodies. Start with snug wraps, check for even spacing, and avoid stacking wraps that create bulk on the hook eye.
