Flywheel Bolt-M12x50mm (E28/E30/E36/E46/E28/E34/E39/Z3) (Genuine BMW)
Part number 11222243051 is a Genuine BMW Clutch Flywheel Mounting Hex Bolt. It is specifically engineered to secure a Dual-Mass Flywheel (DMF) to the engine crankshaft in manual transmission vehicles.
- Dimensions: M12 x 1.5 x 50mm
- One-Time Use Only: These are torque-to-yield stretch bolts. They permanently deform when tightened and must never be reused; doing so can cause the bolt to snap, potentially leading to catastrophic engine or transmission damage.
- Pre-Applied Threadlocker: Features factory pre-applied Loctite/threadlocking compound.
- Torque Rating: Typically tightened to 105 Nm (always verify against your specific engine chassis manual).
- Required Quantity: Most BMW configurations require a matching set of 8 bolts to completely mount the flywheel.
This part number superseded the older hardware number 11221730533 and features incredibly broad compatibility across decades of manual BMW platforms (typically from 05/1986 onward)
