This is a genuine BMW hex Bolt, part number 11 21 1 721 100. The number stamped on the part is 11211721100; BMW's catalog files it under the short number 1721100. You will find it on our Engine shelf, under Crankshaft with bearing.

It fits every E36 body style (318i and 318ti, 1992–1999), with the M42, M43 or M44 engines — and the European-market versions. It also fits the E46 sedan, coupe and touring (316i, 316i 1.6, 316i 1.9 and 318i, 1997–2001), with the M43 engine.

BMW draws it on 10 diagrams, among them Belt Drive-Vibration Damper (11_0334) and Belt Drive-Vibration Damper (11_1385). It weighs about 260 g (0.6 lb).

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