🔌 Function

Secures a stud or bolt at a joint, holding the clamp load on the assembly against the vibration that would otherwise slacken it.

⚠️ Common Signs of Failure

• Nuts found slack, backed off or missing, particularly on mountings and joints that see vibration
• A joint working, knocking or leaking because the fastener has lost its clamping load
• Corroded or seized nuts, or ones that will not undo without rounding the flats
• A locking nut that spins freely down its thread, showing the locking feature is spent

🛠️ Service Notes

• Check the stud or bolt thread is clean and undamaged and run the nut down by hand first; grit on the thread gives a false torque reading
• Tighten to the torque in the workshop manual for your engine, following the specified sequence on multi-fastener joints and working round in stages so the load comes up evenly
• Renew self-locking and all-metal locking nuts rather than reusing them — once the locking feature has been through a cycle it no longer holds reliably
• Fit the washer, tab or locking arrangement that belongs with that joint; a locking device that was bent or crimped in service should be replaced, not straightened and reused
• Marine-grade anti-seize on stainless threads reduces galling and makes later removal possible, but keep it off threads that must take a locking compound
