The research and development of a popular, publicly available microscrew system required an analysis of fastener strength. This analysis was performed using a Finite Element Analysis (FEA) program. ANSYS was used to model and stress the fasteners through various loading schemes. A simplified model was constructed due to limitations in model size.;The analysis required key parameters to be changed slightly. These parameters were socket depth and socket diameter. Changing these parameters had a substantial affect on the strength of the fastener.;Torque and rotation to tension analyses were performed on the microscrew to determine the validity of the ANSYS computation results. This data also provided complimentary information on the mechanics of a threaded assembly.
