🔌 Function

This screw clamps and retains steering-system components in their correct position and alignment. Correct torque and thread condition are essential to keep the assembly secure under continuous vibration and steering loads.

⚠️ Common Signs of Failure

• Loose or backed-out fastener causing play in the steering assembly
• Stripped, stretched or galled threads that will not hold torque
• Corrosion or seizing that makes removal difficult and weakens the shank
• Head damage from previous over-torquing or use of incorrect tools
• Snapped or sheared screw resulting in a detached or shifting component

🛠️ 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
