These precision CNC-machined titanium bolts feature exact OEM BBS thread specifications (M7×1.0mm pitch) with an integrated 12.6mm load-spreading flange and an 8mm 12-point (bi-hex) drive head. Available in standard 24.5mm length (factory fitment for OEM lips and barrels) and extended 32mm length (for stepped lips, thicker custom forged faces, or multi-piece conversions), they guarantee true radial runout and airtight rim barrel sealing.\u003c\/p\u003e\n\n\u003ch3\u003eUnsprung \u0026amp; Rotational Mass Reduction\u003c\/h3\u003e\n\u003cp\u003eA complete set of four 3-piece wheels utilizes between 120 and 160 assembly bolts (typically 30 to 40 per wheel). Swapping factory steel bolts for Grade 5 titanium slashes hardware weight by over 45%. Because these fasteners sit at the outer perimeter of the wheel assembly, reducing peripheral rotating mass noticeably decreases rotational inertia, sharpens turn-in responsiveness, and improves suspension dampening compliance over high-frequency road chatter.\u003c\/p\u003e\n\n\u003ch3\u003ePermanent Corrosion Resistance vs. OEM Chrome\u003c\/h3\u003e\n\u003cp\u003eOriginal BBS chrome-plated steel bolts are notorious for flaking, pitting, and rusting from corrosive metallic brake dust and harsh wheel cleaners. Grade 5 Ti-6Al-4V titanium develops a permanent, natural oxide film that will never rust, tarnish, or suffer galvanic pitting, ensuring your restored show wheels retain their pristine mirror or showroom luster season after season.\u003c\/p\u003e\n\n\u003ch3\u003eKey Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIconic BBS Modular Wheels:\u003c\/strong\u003e BBS RS (e.g., RS001, RS005, RS211), BBS Super RS, BBS LM (Le Mans 2-piece), BBS RC, and BBS RF split wheels.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Piece Aftermarket Rebuilds:\u003c\/strong\u003e OZ Racing, Work, SSR, and custom forged 3-piece wheel conversions utilizing M7×1.0 hardware.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStepped Lip \u0026amp; Custom Barrel Conversions:\u003c\/strong\u003e 32mm extended length accommodates aftermarket forged outer lips and heavy-duty inner barrels.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications \u0026amp; Dimensions\u003c\/h3\u003e\n\u003cp\u003e\n  \u003cstrong\u003eMaterial:\u003c\/strong\u003e Certified Aerospace Ti-6Al-4V (TC4) Titanium Alloy, Grade 5\u003cbr\u003e\n  \u003cstrong\u003eThread Size:\u003c\/strong\u003e M7\u003cbr\u003e\n  \u003cstrong\u003eThread Pitch:\u003c\/strong\u003e 1.0mm\u003cbr\u003e\n  \u003cstrong\u003eFlange Head Diameter:\u003c\/strong\u003e 12.6mm\u003cbr\u003e\n  \u003cstrong\u003eFlange Head Height:\u003c\/strong\u003e 6.0mm\u003cbr\u003e\n  \u003cstrong\u003eDrive Type:\u003c\/strong\u003e 8mm 12-Point (Bi-Hex) Socket\u003cbr\u003e\n  \u003cstrong\u003eAvailable Lengths:\u003c\/strong\u003e 24.5mm (Standard BBS Spec), 32mm (Extended Spec)\u003cbr\u003e\n  \u003cstrong\u003eAvailable Finishes:\u003c\/strong\u003e Natural Titanium, PVD Vacuum-Coated Gold, Rainbow, Burn Blue, PVD Deep Black\n\u003c\/p\u003e\n\n\u003ch3\u003eWheel Assembly \u0026amp; Torque Guidelines\u003c\/h3\u003e\n\u003cp\u003eBefore assembly, ensure rim mating surfaces and silicone seal channels are immaculately clean. Apply a small drop of medium-strength thread locker or anti-seize paste to the leading threads. Always tighten bolts using an 8mm 12-point socket in a progressive criss-cross star pattern across 3 stages, finishing at 18–22 N·m (13–16 lb-ft) or the wheel manufacturer's specific rebuild torque. Always check torque with a calibrated manual torque wrench.
