This bolt type uses one beam element along with a head and nut represented by circular beam spider meshes. This model is beneficial due to the fact that it is simple and fast to design. The drawbacks of this model are that slipping motion cannot be captured between the nut or head. Also, the connection could be too stiff for loads above the service load of the bolt. Other considerations are that only one element can be used for the shank and the material card is limited to *MAT_SPOTWELD.
