What is a Lug Bolt

Wheel Hub Bolt A high-strength bolt used to connect the vehicle wheel. The connection location is the hub unit bearing of the wheel! Generally, class 10.9 is used for mini vehicles, and class 12.9 is used for medium and large vehicles! The structure of the hub bolt is generally a knurled key file and a threaded file! And a hat head! Most of the T-shaped head hub bolts are above 8.8, which bears the large torsion connection between the automobile hub 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.
