Comment: I have a 3\4" drive socket, Snap-On, and is marked: 1/2 B3410-16 USA 8. It has a long slot thru it that is 1/2" wide in it that is 21/2" deep. It also has a 3/4" square hole thru it that is just above the Snap-On numbers and lettering. It weighs almost 2 lbs. It "rings" like a tuning fork when you tap it. I have checked your online catalogs and cannot find it. Please tell me what it is. I cannot find in your online catalog.
HELP in this identification, please
