WF-LB001 Cone Seat Splined Anti‑Theft Wheel Lock Bolts

High-Strength Alloy Steel Material: Manufactured from premium high-carbon alloy steel, such as 35CrMo or 40Cr, providing excellent tensile strength and impact resistance to help maintain structural integrity during long-term use.
Integrated Cold Heading & Precision Machining: Produced through multi-station cold heading forming technology, combined with CNC precision milling of the spline tooth profile, ensuring accurate integration between the threads and anti-theft spline structure.
Multi-Layer Corrosion Protection: Enhanced through heat treatment for improved hardness, with exterior finishes available in chrome plating, black electrophoretic coating, or zinc plating. The surface provides excellent salt spray corrosion resistance and long-term durability.

Unique Spline Anti-Theft Structure: The non-standard tapered spline tooth design significantly increases the difficulty of unauthorized socket duplication, helping prevent forced removal using common tools or gripping equipment.
Precision Cone Seat Positioning: The standard 60° cone seat contact surface provides accurate alignment and close contact with compatible wheel mounting holes, ensuring even load distribution while helping prevent loosening and abnormal noise.
Dedicated Matching Removal Key: Each set is supplied with a specially designed high-strength spline removal socket. The key provides smooth engagement and balanced torque transfer, helping reduce spline wear during repeated installation and removal.

Wheel Modification & Security Upgrades: Widely used for aftermarket aluminum alloy wheel upgrades and theft protection enhancement of valuable OEM wheels.
Multi-Vehicle Compatibility: Suitable for a wide range of passenger cars, sports coupes, and SUVs equipped with compatible cone seat wheel fastening systems.
Challenging Road Conditions & Harsh Environments: Particularly suitable for vehicles parked outdoors for extended periods, vehicles in remote areas, or applications exposed to high humidity, salt spray, and other demanding environmental conditions.
