Nickel Tungsten bead 5/64-inch.

A Nickel Tungsten Bead (5/64") is a high-density fly-tying bead designed to add weight, durability, and a clean, understated finish to nymph and midge patterns. Made from tungsten—significantly heavier than brass—it allows flies to sink quickly and maintain depth in fast or deep water without adding bulk.

The nickel finish provides a subtle metallic sheen that imitates natural gas bubbles or insect flash without being overly bright, making it effective in clear water and pressured fisheries. The 5/64-inch size is ideal for small hooks and compact patterns such as midges, emergers, and slim nymphs, offering excellent balance between weight and proportion.
