Hex Bolt — a genuine BMW part, number 11 21 1 720 633. The number stamped on the part is 11211720633; BMW's catalog files it under the short number 1720633. You will find it on our Engine shelf, under Crankshaft with bearing.

It fits every E36 body style (320i, 323i, 325i, 328i and M3, 1992–1999), with the M50, M52, S50 or S52 engines — and the European-market versions. It also fits the E46 sedan, coupe, convertible and touring (320i, 323i and 325i, 1999–2006), with the M52, M54 or M56 engines — and the European-market versions.

BMW draws it on 9 diagrams, among them Belt Drive-Vibration Damper (11_0335) and Belt Drive-Vibration Damper (11_2177). It weighs about 310 g (0.7 lb).

We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
