Truck Bolt DXTB173 For CHRYSLER

Truck bolts are critical fasteners commonly used in heavy machinery and structures, widely applied in fields such as trucks, trailers, and construction engineering equipment.
Conical head:
This is the most distinctive feature of truck bolts: a short, tapered section beneath the head.
Function: This tapered section can precisely fit into the tapered hole of the connected component, serving the purpose of **alignment and positioning**, preventing the bolt from shaking within the hole and ensuring connection accuracy. Additionally, the tapered surface fit effectively resists loosening caused by vibration.
Extended smooth rod:
Above the threaded portion of the bolt, there is a smooth, unthreaded shank.
Function:
Resisting Shear Forces:
The diameter of the smooth rod matches the nominal diameter of the bolt, allowing it to tightly fill the connecting hole. It primarily functions to resist shear forces perpendicular to the bolt axis, which is the core function of truck bolts.
Prevent Thread Damage:
By transferring shear forces to the stronger shank instead of the relatively fragile threads, this enhances the reliability and fatigue strength of the connection.
```Header style:```
Common head styles include round heads or square necks with round heads.
Function of the square neck: The square neck (located beneath the head) can lock into the workpiece when tightened, preventing the bolt from rotating along with the nut, allowing for one-sided operation (simply tighten the nut).
Thread type:
Typically featuring coarse threads to ensure higher strength and resistance to loosening under heavy loads and vibration conditions.
