The tool used to stabilize screws during surgical insertion is the screw holding forcep. This specialized instrument is designed to grip and hold screws securely, allowing surgeons to manipulate and position them accurately without losing control. Using screw holding forceps ensures that the screws are inserted at the correct angle and depth, which is crucial for the success of the surgical procedure. This tool enhances precision and efficiency, reducing the risk of complications that can arise from improperly placed screws.

Each of the other options serves different purposes in surgical settings and does not specifically contribute to the stabilization of screws during insertion. Intramedullary nails are used for stabilizing fractures within the medullary cavity of long bones, while diamond knives are precision cutting tools used for delicate tissue dissection. A plate bender is used to shape surgical plates for bone fixation but does not assist in holding screws during insertion.
