The choice of this mathematical framework is based on the nature of the loading of the washers and bolt head, which operate primarily in bending when the pre-tensioning force is transmitted through the contact surfaces. The outer washer and bolt head are treated as elastic annular and solid plates with boundary conditions appropriate to the element&#8217;s operation, allowing for analytical evaluation of deflections and determination of the minimum element thickness.
