Hi Sandeep316
The bolt preload is uniform throughout the stud imagine you put one end in a tapped hole and at the other end you tighten a nut against a member face, the thread in the tapped hole sees the same tension as the threaded part in the nut.
We can’t help you any more than that because you haven’t given any info, ie size and length of stud, material and or application of the stud.
