Bolted connections are one of the most ubiquitous forms of connection between engineered components. However, these connections present a degree of complexity that is most often lost in the everyday practice of twisting wrenches. An analytical model was created and programmed using visual basic and was validated with MSC Nastran. This model explores some of these interesting quirks in the science of bolting, such as the use of very diverse material pairs for the internal and external threaded components. Important observations are made with respect to the load distribution of the engaged threads and the effect of varying the engaged (threaded) length or stiffness ration between external and internal threaded components. Different bolt loading situations are analyzed with either a simple pulling action or with preload clamping requirements. Some of the more well known tricks utilized in shifting the load distribution of the engaged threads are also discussed.
