Direct from Baoji Titanium Valley: From ASTM certified hot-forged Gr5 wheel hardware to titanium exhaust and industrial jigs.
In high-stress hub retention assemblies, fasteners endure continuous rotational shearing, dynamic braking heat spikes, and cyclic vibrational loads. Conventional OEM Grade 10.9 or 12.9 chromoly steel wheel bolts exhibit high tensile strengths but are prone to surface oxidation, electrochemical galvanic seizure, and fatigue failure when unsprung weight is pushed to track-level thresholds. As a specialized original manufacturer serving automotive engineering teams and performance speed shops in San Diego, Jovzi Titanium crafts wheel lug bolts exclusively from certified Grade 5 Titanium (Ti-6Al-4V / UNS R56400).
Our proprietary manufacturing procedure integrates continuous-grain hot forging with CNC rolled threads under tight thermal surveillance. Unlike cut threads that sever the crystalline grain orientation of the titanium bar, thread rolling maintains continuous grain alignment along the thread pitch line, boosting bolt fatigue endurance by more than 35%. Ti-6Al-4V delivers a nominal tensile strength of 950–1050 MPa with a yield point surpassing 895 MPa, matching high-grade alloy steel while decreasing rotational, unsprung hub mass by ~45%.

Precision aerospace legacy meets coastal saline environments and premier Southern California motorsport culture.
From track-day preparation at Buttonwillow and Chuckwalla Valley Raceway to high-performance coastal drives, San Diego speed workshops demand unyielding lug integrity. Our hot-forged Gr5 titanium lug bolts dramatically decrease unsprung mass at all four corners, sharpening steering response, turn-in crispness, and brake cooling heat-dissipation.
Available in both 60-degree cone seats and ball seats for Porsche, BMW M-series, Audi RS, and Ferrari platforms.
San Diego’s coastal humidity and persistent Pacific marine layer saturate coastal road vehicles with salt spray. Traditional chrome-plated or black-oxide steel wheel fasteners quickly suffer from galvanic galvanic corrosion, freezing tight to aluminum wheel hubs.
Jovzi Gr5 titanium inherently develops a microscopic, self-repairing titanium dioxide (TiO2) passivation film that completely eliminates rust and aesthetic degradation.
With San Diego’s longstanding defense and aerospace contractor presence, regional engineers demand strict material traceability, documented batch mill test reports (MTCs), and absolute dimensional tolerances.
Our wheel fasteners adhere to aerospace metallurgical methodologies, complete with chemical spectrometry validation and BaoTi Test Center verification on demand.
