Running 10mm or 12mm spacers is serious fitment territory — and at those thicknesses, hardware integrity is non-negotiable. Dinan's 40mm M14x1.25 lug bolt provides the additional shank depth needed to restore full thread engagement through a 10mm or 12mm spacer on F and G chassis BMWs. OEM cone-seat geometry ensures the bolt loads the hub identically to factory spec, and the black zinc-coated steel construction handles road grime and moisture exposure over time. Sold as a set of 10.
Features:
+ M14x1.25 thread, OEM cone-seat geometry — F/G chassis application
+ 40mm shank length, for use with 10mm and 12mm spacers
+ Steel construction, black zinc corrosion-resistant coating
+ Set of 10
Thread sizing: E chassis BMWs typically use M12x1.5. F and G chassis models use M14x1.25. Verify your spacer thickness and chassis thread spec before ordering.
