Sleeve Flanged Wheel Nut

description

1. Performance & Material Properties
   • High-Strength Carbon & Alloy Steel Core – Forged from quenched-and-tempered C1045 carbon steel or 4140 alloy steel for ultimate tensile strength (800–950 MPa) and Rockwell hardness (35–45 HRC), ensuring maximum resistance to shear and pull-off forces on heavy-duty axles.
   • Sleeve-Flanged, Hub-Piloted Profile – Precision-machined flange and internal sleeve accurately center the wheel on the hub pilot diameter, eliminating run-out and reducing bearing wear under high loads and sustained highway speeds.
   • Black Corrosion-Resistant Finish – Trivalent zinc or black-oxide plating (with optional UV-stable powder coat) delivers ≥480 h of salt-spray protection (ASTM B117) in road-salt, coastal or marine environments; custom RAL colors available for fleet branding or phase identification.
   • Optimized Thread Geometry – Rolled coarse threads (e.g., M22×1.5, 1½″–12 UNC) provide smooth engagement, high fatigue life, and self-locking action under vibration; flange face features serrations to maintain clamp load even under dynamic torque cycles.
2. Detailed Application Range
   • Heavy-Duty Truck & Semi-Trailer Wheels – Engineered for single and dual steel wheels on tractors, trailers and vocational vehicles operating in long-haul, regional haul, refuse, tanker and dump applications.
   • Hub-Piloted Single-Wheel Configurations – Ideal for trucks with hub pilot centers, ensuring quick wheel alignment during tire changes and minimizing installation error on the roadside.
   • Marine, Oilfield & Coastal Fleets – Robust plating and steel grades resist corrosion from salt spray and petroleum exposure—perfect for port tractors, offshore rigs and coastal heavy-haul operations.
   • Fleet Maintenance & Custom Builds – Preferred by OEMs and aftermarket distributors for custom wheel-and-tire packages, emergency service vehicles and retrofits requiring precise centering and high clamp-load retention.
3. Effortless Operation & Convenience
   • Tool-Friendly Installation – Fits standard impact wrenches and torque wrenches; flange design accepts open-end or crowfoot adapters for tight spaces, while the sleeve guides each nut onto the stud for fast, fool-proof mounting.
   • Quick Wheel Changes – Hub-piloted sleeve maintains centering as nuts are hand-started, reducing cross-threading and allowing road crews to swap wheels in under 10 minutes per side.
   • Organized Assortment & Kit Options – Available in bulk pails or compartmentalized cases (20–100 pcs) sorted by thread size; optional color-coded sleeves simplify size identification and inventory management.
   • Universal Compatibility – Offered in all industry-standard sizes (M20–M24, 1.5″–1¾″), mating seamlessly with existing wheel studs, lug adapters, and aftermarket stud extenders.
4. Superior Quality & Long-Term Reliability
   • ISO/TS 16949 & SAE J1199 Certification – Manufactured in automotive-grade facilities to ensure dimensional accuracy (±0.1 mm), material consistency, and compliance with heavy-duty wheel-nut safety standards.
   • Rigorous Testing & Traceability – Each batch undergoes torque-to-yield validation, 500 h salt-spray corrosion testing (exceeding ASTM B117), and ultrasonic crack detection; full heat-lot traceability from melt to finished product.
   • Vibration-Resistant Performance – Serrated flange and precision sleeve-pilot combination maintain consistent clamp loads under cyclic loading, highway vibration, and extreme temperature fluctuations.
   • Maintenance-Free Service Life – High-purity steel and advanced plating deliver decades of rust-free, high-torque performance—even in the harshest industrial, off-road, and marine operating conditions.
