⚙️ Key Features

🔌 Function

Holds a component to its mounting, taking up the clamp load that keeps the joint together.

⚠️ Common Signs of Failure

• Screw loose, missing or backed out
• Head corroded or the drive slot damaged
• Thread stripped or cross-threaded
• Component it holds able to move or rattle

🛠️ Service Notes

• Clean the threads in the casting and check them for damage before fitting; a screw run into a dirty or pulled thread gives a false torque reading and will not hold its load
• Tighten to the torque given in the workshop manual for your engine rather than by feel, and follow the specified sequence where the joint has one
• Use the thread locking or sealing compound the manual calls for at that joint — some screws pass into oil, coolant or fuel space and have to seal as well as clamp
• Renew any screw that is stretched, corroded in the shank, or has damaged threads or a rounded head, and never reuse one that was tightened by a stretch or angle-tighten procedure
• A little marine-grade anti-seize helps later removal where the manual permits it, but keep it off threads that are meant to take a locking compound
