Original BMW M10 Flange Nut for 1 Series to 8 Series, M, X, Z4, Z8, and Alpina Models (1995–2025)

Original BMW part 07-11-9-904-670 is an M10 flange nut, a hex nut with an integral flange face, that BMW uses across its 1 Series through 8 Series, M, X, Z, and Alpina models from 1995 to 2025. The flange spreads clamping force over a wider area than a plain hex nut, so the joint holds without a separate washer. BMW's designation for the nut is M10-10-ZNS3, and it carries a chrome-free CR(VI) finish, meaning the coating contains no hexavalent chromium. Each nut weighs 13 grams, and BMW has produced this number since June 2004. The store has long called it a collar nut, which describes the same flanged design.

Original BMW Parts carry a 24-month parts warranty.

This nut is used in a variety of applications on several BMW models, which is why its coverage reaches across so many generations. Within the vehicles covered here, BMW applies it to the E82 and E88 1 Series, the F22 and F23 2 Series, the E90, E92, and E93 3 Series including the S65-powered M3, the F30 and F34 3 Series, and the F32 4 Series. Engine coverage in that group runs from the N51, N52, N54, and N55 six-cylinders to the N20, N26, B46, B48, and B58 engines.
