Original BMW Front Lower Control Arm Hex Nut with Collar M16x1.5 for BMW X3 and X4 (2018–2024)

This Original BMW hexagon nut with collar is the M16x1.5 fastener that secures the front lower control arm on the G01 BMW X3 and the G02 BMW X4, including the F97 X3 M and F98 X4 M. BMW production of this nut began in August 2017. A collared nut carries its own bearing face, which spreads clamping force across the mounting surface it tightens against. This nut is not reusable. Once it has been removed from a control arm joint, fit a new one. It is sold individually, so order one for every joint you plan to open.

Original BMW Parts carry a 24-month parts warranty.

Thread size is the key detail for this nut. This one has an M16 thread with a fine 1.5 mm pitch, which is heavier than the small nuts used on brackets and trim. It is cross-referenced to BMW numbers 31-10-6-789-457, 31-10-6-798-047, and 31-10-6-799-668. One nut type serves gasoline, diesel, and plug-in hybrid versions of both SUVs, so the engine does not change the part.

Common Questions

Can I reuse the old nut after removing the control arm?
No. BMW treats this nut as a replace-only part, so a new one goes on every time the joint is opened.

Does the engine in my X3 or X4 change which nut I need?
No. The same M16x1.5 collar nut covers the four-cylinder, six-cylinder, diesel, hybrid, and M versions of the G01, G02, F97, and F98.
