Troutline Essential Line Classic Tungsten Beads 4.0mm are made for fly tiers who need extra weight for larger nymphs, wet flies and heavy river patterns. Produced from high-density tungsten, these classic beads help flies sink fast while keeping the body compact and well balanced.
The classic round shape is designed for standard nymph and wet fly hooks, including straight-eye and down-eye hooks. Unlike slotted beads, which are mainly used on jig hooks, classic tungsten beads sit neatly behind the hook eye and offer a clean, traditional profile.
The 4.0mm size is a strong choice for heavy nymphs, large Hare’s Ear and Pheasant Tail variants, caddis larva patterns, stonefly nymphs and flies used in deep pools or strong currents. Part of the Trout Line Essential Line, these beads are packed in practical 10-piece bags and offer consistent sizing, clean finish and reliable quality for everyday fly tying.
