Look at the schematic of Hertz's first radio below; He has a single loop spark gap receiver just like Russ's Leedskalnin "Impulse Magnetizer" single loop coil. Running the loop through the board hole surrounded by the hex nuts, then connecting the wire ends of the receiver loop to a spark gap, instead of battery terminals, should allow us to lock those six nuts wirelessly with the Hertz spark gap transmitter!
