Go to your local jobber and buy a magnetic pickup tool. It has a small permanent magnet on the end and it's attached to a telescoping rod, very much like a auto antenna. They are cheap and the magnet is strong enough to lift the nut, even while bumping into things on the way up. The one I bought new must be 20 years old now.
