A screw thread engagement model is used to start the screw threads of one par into its meeting part to prevent loss of either part during transport or the next workstation

• A. True
• B. False
• C. Not specified
• D. Sometimes

Answer: (A)

A screw thread engagement model provides a guided lead-in for starting threads, which helps align the screw with its mating part so the threading begins smoothly. This is especially important when parts are handled between steps or transported, because the lead-in keeps them together and prevents them from becoming misaligned or separated before full engagement. By making the initial entry into the threaded hole easier and more reliable, it reduces the chance of losing either part during transport or at the next workstation. So this use matches what a thread engagement model is designed to do, making the statement true.
