MFC Slotted Tungsten Beads | Perdigon-Style Fly Weights | Montana Fly Company

Overview

Montana Fly Company’s Slotted Tungsten Beads are a practical upgrade for any fly-tyer’s bench. Made from dense tungsten and finished with a polished metallic sheen, these beads add weight where you need it most, helping your nymph patterns sink with control and precision. The slotted design aids in tying, supporting a clean, compact head on perdigon-style flies. Each package includes 20 beads, ready to slip into your next tying session.

Why choose slotted tungsten beads

• Dense tungsten delivers reliable sinking power without excess bulk.
• Slotted construction helps the thread sit flush and keeps the head neat during wraps.
• Wide array of colors lets you match or subtly accent water conditions and lighting.
• Bright, metallic finish adds just the right amount of flash to attract attention without overpowering the pattern.
• 20 beads per package, providing steady supply for multiple patterns.

In practice on the water

These beads are well-suited for perdigon-style flies and bead-head nymphs. The combination of tungsten density and a smooth finish helps patterns cut through current while remaining compact on the shank. The color range offers routing options for rivers, streams, and lake margins where light changes throughout the day.

• Use on perdigon-style bodies to achieve a crisp, weighted profile that sinks faster than lighter heads.
• Pair with contrasting thread colors to create a subtle bead head with a touch of sheen for visibility.

How to use

Slide the bead onto the hook from the eye, with the slot facing up to catch the thread as you build the head. Secure with standard thread wraps, finish with your preferred head cement, and trim excess thread for a clean, durable finish. The bead should sit flush against the shank for a balanced tie that performs in current and drift.
