Motor Mount Asa Torx Bolt, M8x40 - E83 X3 3.0si

This part is listed by BMW as BMW part number 07129904795 (07 12 9 904 795) and is described as a M8x40mm Torx (Asa male) mounting bolt for both motor mounts on 2007-2010 E83 X3 3.0si N52 models. Many BMW bolts cannot be re-used. They stretch when properly torqued and re-using them causes them to stretch even more and could possibly snap the bolt. Unfortunately, there is no way of knowing ahead of time if the bolts are "stretch bolts" so the safest route is to buy new hardware with your parts. These are priced per bolt so order 4 if you're doing both mounts.

This is a Genuine BMW M8x40 Torx bolt with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
