These Dynofit bolts are made from SCM435 alloy steel, treated with a Dacromet-like coating for corrosion resistance, and designed with a 60° conical seat and extended top to improve contact with the wheel face. They’re sold as a 10-piece set intended as aftermarket replacements for applications that require a 45mm shank.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I know these bolts fit my car and wheels?\u003c\/h3\u003e\n\u003cp\u003eCompatibility depends on thread pitch (M14x1.25), the conical seat, and the needed shank length. These bolts suit many BMW F\/G-series and other cars that accept M14x1.25 fasteners and require a 45mm shank—commonly used with 15–20mm wheel spacers or wheels with thicker mounting faces. Always measure existing lug bolts or consult wheel\/spacer specifications before replacing them.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eThread: 14x1.25 (metric fine)\u003c\/li\u003e\n  \u003cli\u003eShank length: 45mm; overall length: 69mm\u003c\/li\u003e\n  \u003cli\u003eSeat style: 60° conical (tapered) seat\u003c\/li\u003e\n  \u003cli\u003eCommon fit: BMW F10\/F30\/F20\/F22 families and similar aftermarket wheels\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and treatments protect these bolts from corrosion and wear?\u003c\/h3\u003e\n\u003cp\u003eDynofit uses SCM435 alloy steel for high tensile strength and subjects the bolts to a salt-spray resistance process comparable to Dacromet, improving rust resistance versus untreated steel. The bolts meet a 10.9 strength grade rating, making them suitable for wheel fastening when installed and torqued correctly. Note: impact tools can damage the protective coating, so use a hand wrench for final torque.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAlloy: SCM435 high-strength steel\u003c\/li\u003e\n  \u003cli\u003eGrade: 10.9 tensile strength\u003c\/li\u003e\n  \u003cli\u003eSurface: Dacromet-style corrosion-resistant treatment\u003c\/li\u003e\n  \u003cli\u003eCare: hand wrench recommended to preserve coating\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow should I install and torque these lug bolts safely?\u003c\/h3\u003e\n\u003cp\u003eInstall by hand-threading each bolt to ensure correct engagement before tightening. Use a calibrated torque wrench and follow your vehicle maker’s lug torque specification; over-torquing risks stretching bolts, under-torquing risks loosening. Because these are extended-length bolts, verify the wheel and spacer clearances and re-torque after the first 50–100 miles of driving.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHand-start bolts to avoid cross-threading\u003c\/li\u003e\n  \u003cli\u003eUse vehicle-specific torque specs with a torque wrench\u003c\/li\u003e\n  \u003cli\u003eRe-check torque after initial driving period\u003c\/li\u003e\n  \u003cli\u003eAvoid impact wrenches on coated surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these replace OEM bolts or work with my spacer setup?\u003c\/h3\u003e\n\u003cp\u003eThey are aftermarket replacements rather than OEM parts and are intended for systems where the stock lug length is insufficient because of spacers or different wheel offsets. Confirm that the spacer thickness (commonly 15–20mm) plus wheel hub depth requires a 45mm shank. If your vehicle originally used shorter bolts, these extended bolts provide the extra engagement needed for safe fastening with spacers.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eNot an OEM direct-equivalent; aftermarket option\u003c\/li\u003e\n  \u003cli\u003eDesigned for wheels\/spacers needing extra shank length\u003c\/li\u003e\n  \u003cli\u003eCommonly paired with 15–20mm wheel spacers\u003c\/li\u003e\n  \u003cli\u003eCheck hub protrusion and thread engagement before use\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: These Dynofit 14x1.25 45mm shank lug bolts are aimed at BMW owners (including many F- and G-series models), Toyota Supra A90 owners, and anyone fitting aftermarket wheels or wheel spacers that require longer M14x1.25 fasteners.
