A machine screw threads into a nut or an insert but unlike a bolt it is meant to be tighted by the head of the machine screw So to clarify a screw makes its own threads and torque is applied to the head a machine screw needs something to be threaded into and torque is also applied to the head a bolt is designed to be tightened by the nut
Jun 08 2018 nbsp 0183 32 However as you can see in the following table both tension and shear are higher in Grade 8 bolts over Grade 5 bolts in fact over 21 higher in shear and 25 in tension The same is true in metric when comparing 8 8 vs 10 9 To be fair the higher the grade of bolt the harder it becomes as rated by the rockwell scale

The rotation of a bolt torque at some point causes it to stretch tension Several factors affect how much tension occurs when a given amount of tightening torque is applied The first factor is the bolt s diameter It takes more force to tighten a 3 4 10 bolt than to tighten a 318 16 bolt because it is larger in diameter
