Hex Flange Nut P1.5 for BYD e2 & More Models, OE 11448291-00

A common fastener fits a broad range of models, which is why the list is long, and why the model name alone will not settle it. Two things decide it: the thread size and the OE number, OE 11448291-00. Compare both against the nut you removed and against your own model and build year in the fitment table on this page. If your car does not appear there, or the thread does not match, send us the vehicle details before you order anything.

Both count, because they describe the same item. This nut carries OE 11448291-00 and also a long code beginning BYDQ, and you will often see the longer code on a parts diagram or an invoice rather than on the nut itself. If either reference matches your paperwork, this is the correct page. Fasteners are rarely stamped, so the drawing you are working from usually matters more than the part in your hand. Send us the code and your vehicle details if neither reference lines up.

Allow 8 to 25 days for delivery, counted from your order to your door. A fastener is usually needed on the day the rest of the work happens, so order it with the parts it belongs to rather than after you have started. If your timing is tight, ask us before ordering and we will tell you where this one currently stands.

It is metal. Nothing beyond that is given, so you will not find a coating or a torque figure from us, and guessing at any of those on a fastener is how joints fail. Take the tightening figure from the documentation for your own vehicle and the assembly it belongs to. Use a new nut rather than the one you removed where the manufacturer calls for it. If you need the specification confirmed before ordering, send us your model and build year and we will ask.

The area given for it is the underbody, so it belongs to work done from beneath the vehicle rather than under the bonnet. Raise and support the car properly before you start looking for it. Only that area is given and nothing more exact, and we will not point you at a specific joint on your own model. Your workshop documentation will show which assembly it belongs to. Before you buy, match your model and build year to the fitment table on this page so you are ordering against the right vehicle.

Because the only line we offer against OE 11448291-00 is the Original/Genuine one from BYD. There is no Aftermarket entry for it, so the page shows one option and the price shown on this page is for that item. With a fastener the important detail is the thread rather than the badge, and the genuine part removes any doubt about it. Check the fitment table on this page, confirm the pitch against the nut you took off, then order. Ask us if you want an equivalent reference looked up.
