Genuine BMW Multi Purpose Bolt

The Genuine BMW OEM Multi-Purpose Bolt (07149503940) is widely used across BMW M-car chassis, most commonly within the rear subframe assembly. On F8X models in particular, this bolt is a highly recommended upgrade over the standard factory version. Unlike the original bolt, which lacks drainage and is known to corrode and seize inside the subframe, this updated design incorporates an integrated water-drain feature that prevents moisture buildup and significantly reduces the risk of the bolt snapping during removal.

Manufactured to BMW’s strict material and strength standards, this bolt ensures correct torque retention, long-term reliability and safe structural performance. It is the ideal choice when refreshing subframe hardware, carrying out chassis upgrades, or replacing bolts that have seized or failed due to corrosion.
