A self-tapping screw is a high-strength one-piece fastener that is driven into preformed holes. The goal of the MQP completed by Leo et al. and the 2006 Research Experience for Undergraduates in Industrial Mathematics and Statistics completed by Miller et al. was to create a mathematical model that allows users to input data about their self-tapping screw and the material it is entering and would output a torque curve which models the fastening process. We improve the algorithm to include the modeling of the failure of the joint as well as a model for the clamp load of the joint. We also investigate a model of heat generation in the screw that includes the speed of screw insertion.
