WF-N258 One-Piece Flanged Dome PCD Lug Nut combines an integrated flange with a closed dome-end profile to provide a practical fastening solution for wheel assemblies. The built-in flange increases the bearing area beneath the nut and helps distribute clamping pressure more evenly during installation. Its PCD-oriented configuration is designed for wheel systems requiring specific bolt-circle and fitment dimensions. The enclosed dome covers the exposed thread end, helping limit contact with road dust, moisture, and debris while giving the wheel assembly a clean finished appearance. It is suitable for passenger vehicles, aftermarket wheels, and various automotive wheel-end applications.

Material: Manufactured from high-tensile alloy steel (e.g., 35CrMo) or premium stainless steel for high yield strength and fatigue resistance.
Precision Machining: Cold-forged and CNC-finished to achieve precise thread engagement (Class 6H/2B equivalents). Vacuum heat-treated for optimized core hardness.
Surface Coating: Finished with Advanced Dacromet, electro-chrome, or black electrocoating to withstand rigorous salt spray anti-corrosion standards.
Integrated Flange Base: Distributes torque evenly across the wheel seating area, significantly reducing stress concentration and loosening risks.
Protective Capped Dome: Seals off moisture, road debris, and salt, preventing thread seizure and internal rusting over time.
Precise PCD Alignment: Formfitted for exact Pitch Circle Diameter placement, ensuring vibration-free rotational balance.
Ideal for high-performance automotive tuning, off-road vehicles, light trucks, and race cars equipped with aftermarket or OEM alloy wheels. Optimized for extreme driving conditions where reliable retention and corrosion immunity are paramount.
