Product Description

PRODUCT PARAMETER

Conical bolt

Conical wheel nuts feature a tapered inner seat that mates with conical wheel bolts, enabling self - centering alignment between wheels and hubs. Made from high - strength steel (Grade 10.9/12.9, often zinc - plated or Dacromet - coated for corrosion resistance), they comply with standards like QC/T 355 and relevant DIN specifications.

Applications:

Passenger Cars & NEVs: Ensure precise wheel - hub connections, catering to the lightweight designs (e.g., aluminum hubs) in electric vehicles.
Commercial Vehicles (Trucks, Buses): Withstand heavy loads and vibrations, crucial for safe operation under high torque.
Aftermarket Maintenance: Replace worn nuts during wheel repairs or upgrades, upholding safety.

The conical design evenly distributes clamping force, resists loosening, and prevents misalignment. Adhering to proper torque (per manufacturer guidelines) is essential to avoid hub damage or loosening, making these nuts indispensable for vehicle wheel - end safety. (≈200 words)
