What it is
Hareline Danville Flat Waxed Thread is a flat, wax-coated fly-tying thread in 210 denier. It lays down smooth, flat wraps that help reduce bulk while still giving you high tensile strength and durability. The wax adds grip so materials stay put when you cinch down.
What to tie with it
This is a go-to thread for large flies, heavy materials, and anywhere you need to really lean on your thread pressure without breaking. It’s commonly used for spinning deer hair, building durable streamer heads, and tying salmon and larger streamer patterns where you want smooth, flat thread bases and solid material control.
Flies and the fish they're for
A common use is spinning deer hair for bass bugs, where the thread strength and waxed bite help pack and flare hair for largemouth and smallmouth bass in ponds, lakes, and rivers. It’s also a natural fit for big, durable streamers and salmon-style flies that get swung or stripped for fish like trout and salmon in rivers, where abrasion resistance and tight, low-bulk wraps matter.
