Genuine OEM factory-original BMW automotive battery hold-down retention bracket and mounting bolt kit (Part Number: 61-21-8-351-011 / 61218351011). This item is brand new old stock (NOS) with the original manufacturer tracking label wrap intact, manufactured in Germany.

This critical battery structural containment kit consists of a long, heavy-duty black-oxide coated steel retention hex bolt paired with a matching cast metal anchor wedge block. It drops cleanly through the battery tray assembly to grab the base lip of the plastic battery casing, locking the power unit firmly to the vehicle frame to eliminate movement, case cracking, and dangerous road-vibration damage.
