Wheel Bolts for Mack

Wheel bolts for Mack

Car wheel bolts are generally made of high-strength steel. The strength grade of the bolt wheels is printed on the head of the truck wheel bolts. There are 8.8, 10.9, and 12.9. The larger the value, the higher the strength. Here, 8.8, 10.9, and 12.9 refer to the performance grade label of the bolt, which consists of two numbers, which respectively represent the nominal tensile strength value and yield ratio of the bolt material, generally expressed by "X.Y", such as 4.8, 8.8, 10.9, 12.9 and so on. The tensile strength of bolts with performance grade 8.8 is 800MPa, the yield strength ratio is 0.8, and the yield strength is 800×0.8=640MPa; the tensile strength of bolts with performance grade 10.9 is 1000MPa, the yield strength ratio is 0.9, and the yield strength is 1000×0.9= 900MPa.

Others and so on. Generally, the strength of 8.8 and above, the bolt material is low carbon alloy steel or medium carbon steel, and heat treatment is called high strength bolt. The tire screws of the car are all high-strength bolts. Different models and different loads have different matching bolt strengths. 10.9 is the most common, 8.8 is generally matched to lower-end models, and 12.9 is generally matched to heavy trucks. superior.

The wheel nut bolt is used for American series truck Mack.
