Adam opens a mailbag from Tested viewer Chris Small, who's been waiting almost two years to send this gift: a set of barrel nut screwdrivers--the same make and models used to install threaded inserts on Navy ship terminals. This mailbag not only introduces Adam to a new tool, but includes a junction box to demonstrate how they work!
