Product Description

PRODUCT PARAMETER

Wheel Hug Bolt

Wheel bolts are high-strength fasteners securing wheels to vehicle hubs, designed to withstand radial/axial loads, torque, and vibration. Made of 10.9/12.9 grade alloy steel (zinc-plated or Dacromet-coated for corrosion resistance), they feature tapered/spherical seats to align with wheel hubs, ensuring tight, centered fits. Standards like DIN 79063, ISO 8665 specify sizes (M12–M14 common) and thread pitches (1.25/1.5mm) for cars/trucks.

Applications:

Automotive: Attach wheels to passenger cars, SUVs, and light trucks (critical for safe acceleration/braking).
Commercial Vehicles: Secure heavy-duty wheels on trucks, buses, or trailers (high-tensile variants handle heavy loads).
Motorcycles: Fasten wheels to frames, with smaller sizes (M8–M10) for lighter loads.
Racing: Use high-performance alloys for enhanced torque resistance during high-speed maneuvers.

Proper torque (per manufacturer specs) is vital—prevents loosening or hub/wheel damage.
