This part is listed by BMW as BMW part number 07149125856 (07 14 9 125 856) and is described as a M8 hex nut used on various battery cables as well as in the engine compartment as the positive battery jumper post. A rusty or corroded post will not allow a good charge or even prevent you from jump starting the car.
This is a Genuine BMW battery nut 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.
