This part is listed by BMW as BMW part number 31106786310 (31 10 6 786 310) and is described as the front inner hex bolt to secure the thrust arm (tension strut) to the subframe on F10 5-series, F06/F13 6-series, and F02 7-series models (with xDrive). It measures M14 x 119mm (or 120mm). BMW requires replacing this bolt and the "clip nuts" any time they are loosened such as when replacing the tension strut or bushings.
This is a Genuine BMW 120mm hex 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.
