Original BMW 22 mm Plastic Cap Nut with Washer, BMW 1–7 Series, M, X, and Z Models (1984–2019)

BMW's 22 mm plastic cap nut with washer is a genuine one-piece fastener used across a wide range of BMW cars and SAVs from 1984–2019, from the E30-era 325e through the 6 Series Gran Coupe. BMW names it a plastic capnut with washer and gives a diameter of 22 mm. Each nut weighs about 1 g. Production of this number began in March 2005. It is made in Germany and sold by the piece. A cap nut closes over the end of its stud, and the built-in washer spreads the clamping load across the panel or part beneath it.

Original BMW Parts carry a 24-month parts warranty.

This number replaced the earlier 07-14-7-166-870, and BMW marks the change as exchangeable retrospectively. That means the current nut can be used where the old number was fitted. Because the same nut appears on so many platforms, the diameter is the detail to check against the part you are replacing. BMW's parts data shows it on chassis families such as the E90, F30, E60, F10, and F22, all of which are covered by the model years in our fitment.
