Firehole Tungsten Stones are precision weight beads for fly tying. They deliver true-to-size metric diameters for accurate fly proportions and reliable depth control in cold and clear water. Each bead is 100% tungsten, providing dense weight that yields fast, controlled sink rates so your pattern remains near the target zone. The bore is clean and uniform, seating smoothly on all hook styles for consistent profiles, pattern after pattern.
Finish options include polished, matte, and plated colorways for durable, corrosion resistant performance in varied water conditions. These beads suit classic nymphs such as pheasant tails and hare's ears, as well as midges and micro-nymphs, and broader attractor patterns. Size range spans 2.0 mm to 4.5 mm in 0.5 mm steps, with pack counts of 24 beads (2.0–3.5 mm), 18 beads (4.0 mm), and 12 beads (4.5 mm).
