In the case of small threads (5mm and lower) or an emergency one can (temporalily) modify a pop rivet tong: Remove the threaded plug, then the spring, then the 2 or 3 claws and the 'mouth'. Then insert from the top opening a bolt with the desired thread (washer under the head) and appropriate lenght. Screw a rivet nut onto the bolt for not losing bolt and washer. (Yes: I have a 2nd tong plus bolts with knurled large heads just for riveting nuts.)
