🔌 Function

The terminal screw provides a threaded fastening or terminal connection point on inlet and exhaust system components, holding the assembly securely in place. Correct fitment and torque maintain a stable joint under engine heat and vibration.

⚠️ Common Signs of Failure

• Corrosion or oxidation on the threads or head preventing proper tightening
• Stripped, rounded or damaged threads that will not hold torque
• Repeated loosening under engine vibration, allowing a joint or connection to work loose
• Seized in place so that removal risks damage to the mating component
• Visible leakage or a loose connection at the joint the screw secures

🛠️ Service Notes

• Four of these screws are used per assembly, so when one shows corrosion or a stripped head it is worth checking the other three, since they see the same heat and vibration and often fail together.
• As a terminal-connection screw on the inlet/exhaust system, check it makes a clean, tight electrical contact as well as a mechanical one — a loose or corroded terminal screw here can present as a sensor fault rather than a fastener fault.
