🔌 Function

Secures and retains components within the steering assembly, maintaining correct clamping force and alignment between mating parts. Loss of this fastener's integrity allows movement or separation in the steering linkage.

⚠️ Common Signs of Failure

• Corrosion or pitting from saltwater exposure, making removal difficult
• Damaged, stripped or seized threads that prevent correct torque being reached
• Repeated loosening in service, producing play or knocking in the steering linkage
• Stretched, bent or sheared shank after over-torquing or shock loading
• Rounded or damaged head preventing proper tool engagement

🛠️ Service Notes

• Clean and inspect the threads in the casting and on the bolt, and check the bolt is the correct length for the hole it goes into — one that bottoms will not clamp, and one that is too short will strip the thread
• Tighten to the torque figure and sequence given in the workshop manual for your engine; where a stretch or angle-tighten procedure is specified the bolt is single-use and must be renewed
• Lubricate or fit dry exactly as the manual states — the same torque figure applied to an oiled thread puts far more load into the bolt than a dry one
• Fit new washers and locking devices, and use the thread locking or sealing compound specified for that joint
• Discard any bolt that is stretched, necked, corroded in the shank or has damaged threads rather than trying to clean it up and reuse it
