Product description
Hub bolts are high-strength bolts that connect vehicles to the wheels. The connection location is the hub unit bearing of the wheel! Most of the T-shaped head wheel bolts are above 8.8 grade, which bears the large torsion connection between the car wheel and the axle! Most of the double-headed wheel bolts are above grade 4.8, which bear the lighter torsion connection between the outer wheel hub shell and the tire.
Even under extreme operating conditions, Jinqiang Wheel Nuts maintain extremely high clamping forces to securely fasten wheels on heavy-duty on- and off-highway vehicles.
Jinqiang wheel nuts are rigorously tested and certified by independent agencies and certification bodies.
