PinkieStrong C Clamps TL;DR - You will need a 1/2"-13 NC tap - This are pretty much decorative clamps, they start to bind at 15-20 pounds of force. That said, they work as cable guides or [very] light wood working. Both clamps have a 3/4" (19mm) pad and 1 7/8" (47.5mm) range. The small clamp has a 1.5" (38mm) reach. The deep reach clamp has a 3.5" (89mm) reach. DON’T use much infill, stock (15%-20%) is fine. Print with support from the bed. Tap the thread (alcohol works as a lubricate), screw in the bolt and press on the pad. The reason for needing a tap is (on my printer with the filaments I use) there are typically little blobs of plastic in the thread. You may be able to clean the thread with a metal bolt, especially if you file a groove in it. https://www.youtube.com/watch?v=PT4sZC2u_c0
