E46 M3 Axle to Differential Bolt

We use these bolts on all of our E46 M3 race cars, rather than the stock Torx head bolts.

M10x1.5 45mm, Class 12.9, Zinc-Plated Coated and Dyed Blue.

Replaces BMW Part Number: 33211227664

It’s difficult to get a Torx socket over the stock bolts with the axle’s rubber CV boot in the way.  We’ve found using these Allen bolts with a long Allen driver is far easier to torque to spec and less likely to round the head.  Uses an 8mm Allen drive.

We also recommend installing with blue thread locker, loosening axle bolts is a common issue with race cars.

Sold individually, you need 12 to replace all the stock bolts.

Fits E46 M3 with stock OEM axles.
