Late M42 Timing Case Deflector Rail screw

[AmosCake]

Anyone know what screw can substitute for the M6x35mm needed for the swap? This part number 07119919824, is no longer available.
Thanks in advance

Maybe most any socket or probably standard hex head M6x35 bolt and a washer or a bolt with a captive washer? From the pic of the part it looks like a 10-15mm non threaded area above the threads, but that's probably not needed, and a grade 8.8 bolt would be great, but is probably overkill. But I feel like you basically answered your own question since you already have the bolt spec.

You can also use a site like ECS tuning and search M6x35 to see the closest match pretty quickly, or any typical hardware vendor.

Yeah I pretty much knew the spec, was wondering if it had to be a minimum grade since it’s for the timing case and don’t want that bolt being too weak. Thank you!! I’ll look for a 8.8 grade cause fuck it

For the most part, any socket cap grade 8.8 screw should be fine. If you look at any of the other M6 socket cap screws in there, you should see "8.8" stamped on the rim of the socket. The OEM ones are passivated with yellow zinc chromate, but since these are inside an oily engine, they should not rust if you can only find uncoated ones. McMaster Carr should have coated ones that are exactly what you need.

Grade 12.9, zinc plating. $10 for 50. Should have you covered.

Perfect! Thank you!

Question, I would need two of these to replace the sprocket with the deflection rail correct? I see people list only one on parts lists but the bolt that comes with the stock sprocket they claim to reuse is m8x40 I believe

[bmwman91]

Correct, the sprocket uses an M8 bolt. You can reference between these two diagrams for parts and quantities.
E30 w/ sprocket: https://www.realoem.com/bmw/enUS/sho...diagId=11_4367
E36 w/ rail: https://www.realoem.com/bmw/enUS/sho...diagId=11_1370

Also I edited my above post with a McMaster link that should meet your needs.

Thank you so much for your help specially with the links! I really appreciate it
