Lost a bolt, rounded one off, or just tired of silver hardware behind dark wheels? You do not need to go back to the dealer for a single bolt, and you do not need to guess on length.
Dinan 27mm lug bolts (part number D220-0001) are M14x1.25 cone seat bolts for use without wheel spacers (factory length) on F and G-chassis BMWs. Same thread and seat style as your factory bolts, finished in black zinc. Set of 10, enough for one axle on a 5-lug BMW.
Factory Length Dinan 27mm Lug Bolts
Dinan sizes its bolts to the spacer, and 27mm is the length for no spacer at all. It is the factory length for BMW F and G-chassis wheels mounted straight to the hub. If you are adding spacers, this is the wrong bolt: go longer. Dinan's ladder runs 30mm for 2mm and 3mm spacers, 33mm for 4mm and 5mm, 40mm for 10mm and 12mm, 45mm for 15mm and 17mm, and 50mm for 20mm.
The bolt also has to match your wheel's seat. These use an OEM-style cone seat. BMW factory wheels are typically cone seat, but some aftermarket wheels use a ball seat or need different hardware, so check your wheel spec before ordering. Construction is steel with a black zinc coating for corrosion resistance and a finish that disappears behind dark wheels.

Vehicle Fitment
Dinan specifies M14x1.25 bolts by chassis family. Use this 27mm length with no spacer on:
- BMW F-Chassis: 5x120 bolt pattern, M14x1.25 lug bolts
- BMW G-Chassis: 5x112 bolt pattern, M14x1.25 lug bolts

Not for E-chassis BMWs (M12x1.5 thread), wheels with a ball or flat seat, or any car running wheel spacers.
Installation Notes
A direct swap for your existing bolts. No special tools beyond a torque wrench and the correct socket. Change them one at a time if you are only replacing hardware, so the wheel stays located.
- With the car supported on jack stands, fit the wheel directly to the hub.
- Thread all five bolts in by hand until the cone seats contact the wheel.
- Snug in a star pattern, lower the car and torque to your BMW's factory wheel bolt specification.
- Recheck torque after the first short drive.
