I personally used a 2.5" x 1/4-20 socket head screw, with a 1" x 3/8 coupling nut as a spacer and a stack of washers. The screw was sent through the washers and coupling nut, into the nutsert so it just starts to thread into it. I then inserted the nutsert into the hole, held it in place by the coupling nut with a crescent wrench, and turned the socket head screw with a hex head & socket wrench. Doing it manually helped me control the torque a bit more, and I had a better sense of when it was set. Instead of overtorquing it and risking the headache of extracting a damaged nutsert.
