Original BMW Valve Cover Collar Screw M6x30 for BMW 1–8 Series, M2, M3, M4, X1, X3, X4, X5, X6, and Z4 (2009–2024)

This Original BMW collar screw is the M6x30 fastener that clamps the valve cover, which BMW calls the cylinder head cover, to the cylinder head on N55, B46, B48, B58, and S55 engines in BMW 1 through 8 Series, M2, M3, M4, X1, X3, X4, X5, X6, and Z4 models from 2009–2024. A valve cover bolt holds the cover down against its perimeter gasket so oil and crankcase vapor stay inside the head. BMW names this part a collar screw because the bolt carries a built-in flange under the head that spreads clamping load across the cover. The thread is metric M6 and the length is 30 mm. It is sold individually, so you can replace one damaged or missing bolt or order the full count your cover needs.

Original BMW Parts carry a 24-month parts warranty.

Part 11-12-9-454-322 replaces the earlier number 11-12-7-576-310, and BMW rates the change as exchangeable retrospectively, so the newer screw goes on cars originally built with the older one. BMW shows production of the current number starting in March 2019. One screw covers several engine generations, which is why the same part serves N55 cars such as the 335i and 535i, S55 cars such as the M3 and M4, and later B48 and B58 cars such as the 330i, M340i, and 840i.
