Tee nut with "setting tool". Use the setting tool instead of the "hammer" setting tool.
After the correct size hole (diameter or slightly larger than the shaft on the tee nut) is drilled through the material, the setting tool is inserted on the opposite side of the material from which the tee nut was inserted, a few threads started, and the handy dandy drill (preferably a cordless one, complete with clutch) slowly pulls and sets the teeth into the material, hopefully just right and flush. Of course this system has its thickness limitations. Material thickness is limited in order to catch a few threads on the tee nut. May not work on the old 2x4 etc. Then I guess you'd have to get out the all thread, nuts, and a few washers.
