Dinan Lug Bolts - Cone Seat - M12x1.5 - 50mm - Black (Set of 10)

When you're running a spacer thick enough that standard-length lug bolts no longer reach full thread engagement, extended hardware becomes mandatory. Dinan's 50mm M12x1.5 lug bolts are the solution for older BMW platforms running 10mm or larger spacers — providing the additional shank length needed to achieve safe thread engagement through both the spacer and into the hub.

Cone seat design matches the ball seat taper of BMW alloy wheels across E-series and early F-series 5-bolt fitments. Black oxide finish resists the salt, moisture, and brake dust that attack exposed lug hardware in the wheel well. At 50mm shank length, these work with spacers in the 12-20mm range depending on wheel pocket depth — always verify with a thread gauge after test-fitting. Sold as a set of 10.
