It is sold individually, which makes it the straightforward answer to a lost bolt, a stripped thread, or a spacer installation that needs one or two extra fixings to make up a set.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eChoosing The Right Length\u003c\/h3\u003e\n\u003cp\u003eBolt length is dictated by wheel and spacer thickness rather than by model. As a rule of thumb, a bolt should engage the hub by at least the diameter of its own thread. The 38mm bolt suits most aftermarket wheels fitted without a spacer, while the 41mm length covers thicker wheel faces and thin spacers. Where a thicker spacer is fitted, MMX supplies longer bolts within its spacer kits.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eCorrect Seat Profile Matters\u003c\/h3\u003e\n\u003cp\u003eA tapered, or conical, seat bolt must be matched to a wheel with a tapered bolt seat. Fitting a tapered bolt into a ball seat wheel, or the reverse, leaves the wheel located on a fraction of its intended contact area and can allow it to work loose. The seat profile of the existing bolts should always be checked before ordering.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eM14 x 1.25 thread – the common BMW fitment\u003c\/li\u003e\n\u003cli\u003e60° tapered (conical) seat\u003c\/li\u003e\n\u003cli\u003eChoice of 38mm or 41mm shank length\u003c\/li\u003e\n\u003cli\u003eSold individually as a spare or to complete a set\u003c\/li\u003e\n\u003cli\u003eCorrectly torqued to 120Nm on installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Numbers:\u003c\/strong\u003e MMR37-1500-38MM (38mm), MMR37-1500-41MM (41mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread:\u003c\/strong\u003e M14 x 1.25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat:\u003c\/strong\u003e Tapered \/ conical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As:\u003c\/strong\u003e Single bolt\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBMW models using M14 x 1.25 tapered seat wheel bolts\u003c\/li\u003e\n\u003cli\u003eSuitable as a replacement or supplementary bolt for MMX wheel spacer kits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eHow many bolts are needed per wheel?\u003c\/strong\u003e\u003cbr\u003eFive on the majority of BMW applications.
