⚙️ Key Features

  • For engines from serial number 2100285979 onwards
  • 0.002 kg
  • Replaces 422178, 4804445, 4804448, 846384 and 921980
  • 350 applications across six engine families
  • Quantity varies by assembly, most commonly one

🔌 Function

Clamps a small bolted joint, holding the assembly tight against the screw or stud thread.

⚠️ Common Signs of Failure

  • Flats rounded off by a slipping spanner
  • Thread stripped so the nut will not pull up
  • Corrosion seizing the nut on the stud
  • Fastener backing off and the joint working loose

🛠️ Service Notes

  • Two of the numbers it replaces, 4804445 and 4804448, also point to fitting nut 956984 - an order raised against either old number may need both parts, not one or the other
  • At 2 grams this nut is the same published weight as several others in this group, so use the serial number breakpoint and the position, not the mass, to identify it
