Description

WG7121340130​ is a rear wheel bolt with nut​ assembly, whose core mission is to rigidly lock the wheel to the hub. It is a critical load-bearing component for vehicle driving safety.

1.Core Functions

1.Rigid Connection and Torque Transmission
It clamps the rear wheel rim,brake drum/rotor,and hub​ together into a single unit under high preload. As the final link in the power transmission chain, it is responsible for transferring the driving torque​ from the drive axle and the braking torque from the braking system to the wheel, while withstanding enormous shear forces.

2.Load Bearing and Stress Handling
The vehicle's weight and payload are ultimately transferred to the wheel through the wheel bolts. During cornering, they must withstand significant lateral loads; on rough roads, they also endure alternating impact loads, preventing relative movement between the wheel and hub.

3.Safety and Loosening Prevention
Working in conjunction with lock nuts or self-locking features, it utilizes the thread's self-locking property to maintain preload under long-term vibration conditions, preventing bolt loosening that could lead to wheel detachment (a critical safety hazard).

2.Key Features and Selection Notes

1.Specification Matching: This part typically corresponds to large-diameter fine-pitch threads like M23×1.5, with a length of approximately 108mm. It must strictly match the original vehicle specifications and cannot be interchanged.

2.Strength Grade: Rear wheel bolts for heavy trucks usually require a Grade 10.9​ or higher to prevent plastic deformation or fracture under high preload.

3.Installation Specification: A torque wrench​ must be used to tighten the bolts in multiple stages and in a crisscross pattern to the manufacturer's specified torque (typically several hundred N·m). It is strictly forbidden​ to use an impact wrench directly, as this can over-stretch and weaken the bolt.
