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! Generally, class 10.9 is used for mini-medium vehicles, class 12.9 is used for large-sized 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 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.
Designed for flat steel rims, they won’t come loose on their own when properly assembled.
Jinqiang wheel nuts are rigorously tested and certified by independent agencies and certification bodies.

high-strength bolt thread processing

Bolt threads are generally cold processed, which is limited by factors such as thread accuracy and whether the material is coated or not. Rolled thread refers to a processing method that uses plastic deformation to form thread teeth. It uses a rolling die with the same pitch and tooth shape as the thread to be processed. While extruding the cylindrical screw blank, the screw blank is rotated, and finally the tooth shape on the rolling die is transferred to the screw blank to make the screw thread. take shape. The common point of rolling thread processing is that the number of rolling revolutions does not need to be too much. If it is too much, the efficiency will be low, and the surface of the thread teeth is prone to separation phenomenon or random buckle phenomenon. On the contrary, if the number of revolutions is too small, the diameter of the thread is easy to be out of round, and the pressure at the initial stage of rolling is abnormally increased, resulting in a shortening of the life of the die.
