Tungsten beads  JIG Off are used on jig hooks, but they can also be used for nymph hooks.
The fly in the water column always floats with the point up. So the flies will always sink down with the heavy side of the bead down and the hook point facing upwards. That prevents very often catching flies on the bottom. When you tie the thorax on flies the thorax must be tied on the side of the bend of the hooks.
