DIN980V High Performance 304 Stainless Steel Wheel Nut Lock Nut

Product Description

Standard:DIN980V

Our 304 stainless steel wheel nuts are premium automotive fastening components engineered for exceptional corrosion resistance, durability, and safety—designed to securely fasten wheels to hubs for a wide range of vehicles. Crafted from high-grade 304 stainless steel (A2 stainless steel, 18-8 Cr-Ni alloy), these wheel nuts combine the material’s natural anti-rust properties with precision manufacturing, making them ideal auto parts for aftermarket replacement, OEM supply, and high-demand applications where harsh environments or long-term reliability are critical.

Core Features:

1. Superior 304 Stainless Steel Material: Made from authentic 304 stainless steel (compliant with ASTM A240/A480 standards), featuring 18% chromium and 8% nickel content. This alloy delivers outstanding corrosion resistance, rust prevention, and oxidation resistance—far exceeding carbon steel in humid, coastal, rainy, or chemical-exposed environments. It also offers excellent tensile strength (≥515 MPa) and impact resistance, ensuring no deformation, cracking, or failure even under high speeds, rough terrain, or heavy loads.
2. Premium Surface Finishing: Available in natural brushed, mirror-polished, or optional passivated/electropolished finishes (custom galvanized coating available upon request). The surface treatment enhances the material’s inherent anti-corrosion performance, maintains a sleek appearance, and prevents discoloration over time—ideal for vehicles requiring both functionality and aesthetic consistency.
3. Precision Engineering & Perfect Fitment: CNC-machined threads (e.g., M12x1.5, M14x1.5, UNC 1/2-20, UNF 9/16-18) with strict dimensional tolerance control (ISO 9001 certified) ensure tight, wobble-free engagement with wheel bolts and hub studs. Available in conical seat, flat seat, spherical seat, or flanged seat designs to match different wheel rim specifications, enabling easy installation with standard tools and long-term stability without loosening.
4. Wide Compatibility: Suitable for most passenger cars, SUVs, light trucks, recreational vehicles (RVs), boats, and off-road vehicles. Perfect for vehicles operating in coastal areas, wet climates, or industrial zones where rust is a common concern. Custom thread sizes, seat types, and configurations are available for specific vehicle models or specialized applications (e.g., modified cars, commercial fleets).
5. Rigorous Quality Assurance: Complies with international automotive standards (SAE J1199, DIN 934, ISO 898-1) and undergoes strict quality inspections: salt spray test (≥48 hours for natural 304, ≥100 hours for enhanced finishes), torque test, thread accuracy check, and tensile strength verification. Each nut meets safety requirements to eliminate wheel detachment risks.

Packaging

Carton Packaging	Outer Cartonbox Packaging	Pallet Packaging
Bolts are packed in neutral packaging boxes, with standard quantities arranged in small cartons. The exact number of units per carton will be confirmed with the customer to align with their specific requirements. Customized packaging configurations are available upon request.	The small cartons are then consolidated into larger master cartons for secure transportation and storage. The quantity per master carton can be customized based on client specifications or aligned with standard logistical requirements.	The palletized units are securely wrapped with waterproof film and reinforced with packaging straps. Customer-specific shipping marks or labels are affixed to each pallet, ensuring clear identification and compliance with logistics requirements. This final packaging stage guarantees weather-resistant protection and stability during transportation.
