⚠️ Common Signs of Failure

• Thread damaged, galled or stretched
• Corrosion locking the nut so it will not undo cleanly
• Flats rounded off by a slipping tool
• Locking feature no longer holding

• Fit to the specified torque - a propulsion nut left loose will damage far more than itself
• Renew rather than reuse if the nut has any locking feature or has been stretched
• Clean the thread and check its condition before assembly
