🔌 Function

The screw clamps and secures engine components together, maintaining the correct preload at the joint. Using the specified original fastener ensures the joint retains its designed clamping force under engine vibration and thermal cycling.

⚠️ Common Signs of Failure

• Corrosion or pitting of the head and threads in the marine environment
• Rounded or damaged head preventing proper socket engagement
• Damaged, stripped or seized threads on removal
• Loss of torque, with the fastener working loose under vibration
• Stretched or fractured shank after over-torquing or fatigue

🛠️ Service Notes

• Check the head, threads and seating face before reuse; a screw with rounded flats, a stretched thread or heavy corrosion should be renewed, not refitted
• Clean the threads and the mating face so the screw pulls down onto metal rather than onto dirt or old sealant
• Use a correctly sized spanner or socket fully engaged on the head, and support the component so the screw is not loaded sideways as it tightens
• Refit the same washers, locking devices or sealing compound that were originally used
• Tighten to the figure and sequence given in the workshop manual for your engine, pulling the screws of a multi-screw joint down evenly in stages
