The question which comes to our mind is how to make the nuts stronger so that the fastener can bear the tension load and torque. The solution is simple by making the nut height taller. The next question which comes to our mind is whether there is a difference or no. The answer is there is not much difference. When you use a bolt and nut for a joint and there is breakage in the joint it lead to bolt failure. When a bolt failure occurs then repair has to be forthcoming. Nut failure is more dangerous. Many engineers and designers think that joints are secure but in really they are stripped.

If we go by the general rule of thread engagement then the length of the mating part should be around one major diameter. By the rule of book 0.75D is measurement, but this does not take into account the taper, starting threads, bell mouthing. Nuts which have an insufficient length of engagement usually show the thread to bend under load. When the load is repeated and increased it leads to the failures of the threads.

The nut usually fit in the design but the problem of thread shear failures may causes the engineers and designer to think about increasing the height of the nut. If this also does not work then the reason is the nut threads as it can't bear the load at the same amount at equal intervals.

It's very essential for the engineers and the designers to calculate the amount of the shear that a thread may be carrying. He has to remember that assumption that the threads have not been deformed and no radial expansion has taken place. This calculation will cause a higher yield than the real values. When a nut is loaded it begins to dilate at a lower rate than it does from the top. The expansion decreases the amount of the Stronger Nuts is required for lasting long.
