This is a genuine BMW threaded bolt, part number 07 14 9 168 392. The number stamped on the part is 07149168392; BMW's catalog files it under the short number 9168392. You will find it on our Supplies & Hardware shelf, under Group 14. It supersedes the older number 7032350, so a part carrying that number is the same part.
It fits the E46 convertible (323i, 325i, 330i and M3, 2000–2006), with the M52, M54 or S54 engines — and the European-market versions.
BMW draws it on 4 diagrams, among them Safety Belt Front Left (72_0385) and Safety Belt Front Right (72_0386). It weighs about 10 g (under 0.1 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
