Which tool is used to provide controlled torque in screw fastenings?

• A. Needle holders
• B. Suture scissors
• C. Screw tap
• D. Torque ratchet

Answer: (D)

Controlling how tight a screw is tightened is essential to avoid damaging threads or material. A torque ratchet provides exactly that by delivering a preset torque and signaling (often with a click) when that limit is reached, so you stop at the correct tightness. The other tools don’t manage torque: needle holders grip needles, suture scissors cut sutures, and a screw tap creates or mates with threads but isn’t used to apply controlled tightening to a fastener. Hence, the torque ratchet is the tool designed for controlled torque in screw fastenings.
