Modeling the Bolt and Preload

Evaluation of the structural integrity of assemblies often involves proper modeling and analysis of bolted connections, including the consideration of bolt preload effects. The preload on bolts makes it possible for forces to be transferred between clamped parts effectively, whereas loose bolts may cause failure. Preloaded bolts are also often used in applications with liquids to prevent leakage, so bolt preload is a necessary component of such simulations.
