Product description

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.
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.

Selection of high-strength bolt raw materials

The correct selection of fastener materials in fastener manufacturing is an important part, because the performance of fasteners is closely related to its material. Cold heading steel is a steel for fasteners with high interchangeability produced by cold heading forming process. Because it is formed by metal plastic processing at room temperature, the deformation amount of each part is large, and the deformation speed is also high. Therefore, the performance requirements of cold heading steel raw materials are very strict.
(1) If the carbon content is too high, the cold forming performance will be reduced, and if the carbon content is too low, it will not be able to meet the requirements of the mechanical properties of the parts.
(2) Manganese can improve the permeability of steel, but adding too much will strengthen the matrix structure and affect the cold forming performance.
(3) Silicon can strengthen ferrite to reduce cold forming properties and material elongation.
(4) Other impurity elements, their existence will cause segregation along the grain boundary, resulting in the embrittlement of the grain boundary, and the damage to the mechanical properties of the steel should be reduced as much as possible.
