Tetrahedral mesh would normally be produced, the element quality on threads need to be check carefully, fine mesh needs to be used on the threads.

Good geometric representation of stiffness if mesh is fine enough.

Full thread on bolt and nut are modelled.

A simple eight-bolt flange model is used for assessing the different methods. This blog summarises eight methods for modelling bolts in ANSYS 15.0. How one prepares the bolt geometry is an essential factor that will influence the subsequent modelling techniques including meshing, contact and analysis settings. – Step 3: Apply in-service loads to structures – Step 2: Lock the defined bolt pretension load

Mesh: Minimum DOF for best representation/ Hex or Tet.

Prepare geometry: bolt and associated components.

The approach to modelling bolts usually involves undertaking the following: Therefore, efficient methods to model bolts are always desirable.

Modelling bolts for three-dimensional finite element applications has always been a tricky proposition because the details of bolt geometric features usually result in large model size and high computational cost. Bolted joints are commonly used to assemble mechanical structures.
