I am having trouble calculating the axial load carrying capacity of a shoulder bolt. I want to install and torque a shoulder bolt into a member, and occasionally, apply a load underneath the head of the shoulder bolt, putting the bolt in tension. The bolt will not be taking any shear load, and will only be used intermittently to take the axial load.

Initially, I had thought that the axial load carrying capacity is the difference between the proof load and the preload (preload due to torquing the fastener), however, after more research, I believe that is not the case. I think bolt stiffness and member stiffness matter in this case, however, my engineering design book from college does not cover this scenario. It only covers cases of two members being clamped by a nut and bolt, or a member being clamped to another member by means of a bolt and threaded hole.

Does anyone have any experience in this scenario for a shoulder bolt?

Your shoulder screw manufacturer can provide the max load info.




The worst suggestion of your lifetime may be the catalyst to the grandest idea of the century, never let suggestions go unsaid nor fail to listen to them.
