Open Access Graduate Research Paper


The problem of this study was to identify and explain the observable threaded fastener torque difference obtained during assembly installation (known as dynamic assembly torque) and the inspection torque obtained after assembly installation (known as static inspection torque). Casual observations between dynamic and static torque difference are subjective and contain individual bias. Quantitative methods must be utilized to insure that conclusions are well founded and that torque differences observed are justifiably compared. For this purpose: (a) Confidence levels must be established that determine the degree of risk that is undertaken for concluding an erroneous decision and (b) inferential statistics must interpret the facts to determine whether dynamic torque is different than static torque.
