This heat treated 12.9 grade carbon steel lug wheel bolt enhances ultimate tensile strength of ordinary carbon wheel fasteners, specially produced for OEM original car hub replacement and heavy-load modified passenger vehicle wheel assembly. After strict quenching & tempering heat treatment, thickened solid bolt rod and impact-resistant widened head greatly improve ultimate load limit, eliminating bolt fracture risk under heavy-load modified wheel high-speed driving and long-distance travel. Ultra-precision forged rolling threads avoid sliding under long-term highway dust, road mud and alternating dry-wet driving environment. Multi-layer composite anti-rust surface coating resists rainwater, highway sediment and seasonal atmospheric corrosion for family refitted vehicles. Applied for OEM original car wheel rim replacement, heavy load modified sedan hub installation and auto wheel metal hardware splicing. Conventional standard OEM matching sizes ready for delivery, custom heat treatment strength & dimension bolts acceptable, serving as high-strength original replacement metal fastener for heavy-duty modified passenger car wheel hubs.
| Aluminum | Excellent thermal/electrical conductivity but naturally soft. May produce gelatinous buildup during processing. |
| Titanium | EDM machining recommended. Requires deionized water to control heat during processing. |
| Steel | Very strong metal. Wire cutting machines often preferred for complex features. Requires heat management. |
| Brass | High tensile strength, easy to machine but requires slow cutting speed due to softness. |
