This M12x1.25 Flange Nut is a high-strength OEM replacement specifically designed for the GY6 engine platform.

Primary Applications:
- Clutch Assembly: Secures the clutch bell/assembly to the transmission output shaft.
- Flywheel/Magneto: Holds the flywheel in place on the crankshaft (located between the flywheel and cooling fan).

Tech Tip: These nuts are often "one-time use" in high-performance applications as the threads can stretch under the high torque required (approx 40-45 ft-lbs). Always use a drop of medium-strength thread locker to ensure the nut does not back off during operation.
