UTC Thread wax is designed for all nylon fly tying threads. It is a special light formula that prevents fraying of the thread and helps add bite to the thread. The added bite helps hold delicate materials in place with a minimum of thread wraps. This is particularly important when tying small flies. It is also useful when used as a dubbing wax with very fine dubbings.

Fly tyers with rough skin on their fingers will find that the wax also helps in making the handling of materials much easier.
