In today's video blog post we will understand what is meant by bolts of uniform strength. In this case its the shear strength.
In most cases the bolts are or might be weak at the thread section. So to compensate for the loss of strength due to material being removed from the bolt. Its important that the core diameter should be the same as the shank diameter in case of partially threaded bolts.
Please look at the video from Ekeeda to understand in an elaborate manner.
