Okay, the user wants me to translate "tie-rods" into Thai. Let me check if "tie-rods" is already in Thai. No, it's in English. So I need to translate it. The correct Thai term for tie-rods is "แท่งยึด" which refers to the structural components used in construction or machinery. I should make sure there's no other possible translation. Yep, "แท่งยึด" is the standard term. Just output that without any explanation.
