Now the factory bolts are 10mm short of where they need to be, and \"close enough\" thread engagement is not something you want holding a wheel on at 100 mph.\u003c\/p\u003e\n\u003cp\u003eDinan 40mm lug bolts (part number D220-0005) are the M14x1.25 cone seat bolts Dinan specifies for its 10mm and 12mm wheel spacers on F and G-chassis BMWs. Same thread and seat style as your factory bolts, with the extra length a spacer demands. Set of 10, enough for one axle on a 5-lug BMW.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eChoosing the Right Length: Dinan 40mm Lug Bolts\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eLug bolt length is not one size fits all. It depends on how thick your spacer is. Dinan's ladder is simple: 33mm bolts for 4mm and 5mm spacers, 40mm bolts for 10mm and 12mm spacers, 45mm bolts for 15mm and 17mm spacers. These 40mm bolts are the match for Dinan's 10mm 5x112 spacer.\u003c\/p\u003e\n\u003cp\u003eThe bolt also has to match your wheel's seat. These use an OEM-style cone seat. Most BMW factory wheels are cone seat, but some aftermarket wheels use a ball seat or require 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.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e10 x Dinan lug bolts, M14x1.25, cone seat, 40mm, black\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eM14x1.25 thread, the pitch used on BMW F and G-chassis\u003c\/li\u003e\n  \u003cli\u003eOEM-style cone seat\u003c\/li\u003e\n  \u003cli\u003e40mm length, for use with 10mm and 12mm spacers\u003c\/li\u003e\n  \u003cli\u003eSteel construction with black zinc coating\u003c\/li\u003e\n  \u003cli\u003eSet of 10 (one axle); order two sets for four corners\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eVehicle Fitment\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eDinan's application guide specifies M14x1.25 lug bolts for:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eBMW F-Chassis (5x120 \/ M14x1.25)\u003c\/li\u003e\n  \u003cli\u003eBMW G-Chassis (5x112 \/ M14x1.25)\u003c\/li\u003e\n  \u003cli\u003eBMW F9x M5 \/ M8 and F48 X1 \/ F39 X2 (exceptions that use the G-chassis fitment of 5x112 with M14x1.25 bolts)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eUse this 40mm length only with a 10mm or 12mm spacer.
