Original BMW M7x35 Torx Screw for N51, N52, and N52N Valve Cover, BMW 128i, 328i, 528i, X3, X5, and Z4 (2006–2013)

Original BMW part 11-12-7-558-450 is the M7x35 Torx screw that clamps the valve cover to the cylinder head on N51, N52, and N52N six-cylinder engines in the BMW 128i, 328i, 528i, X3, X5, and Z4. BMW names it a Torx screw. The M7x35 designation means a 7 mm metric thread and a 35 mm length. Each screw weighs 20 g, and BMW began producing this number in June 2006. It is made in Germany. Valve cover screws pull the cover down evenly onto its gasket so the cover seals against the head along its full length.

Original BMW Parts carry a 24-month parts warranty.

BMW's parts data ties this screw to the N51, N52, and N52N engines rather than to a single chassis. Those engines appear in the E82 and E88 1 Series, the E90, E91, E92, and E93 3 Series, the E60 and E61 5 Series, the E83 X3, the E70 X5, and the E85, E86, and E89 Z4. The screw is sold individually, so order the number of pieces your cover requires.
