This paper discusses the general principles governing the action of free spinning, self-locking bolts. The concept presented is that the bolt, and the parts it holds, acts as a spring, and it is shown that this leads logically to measuring the work done to remove a self-locking bolt as well as measuring its breakaway torque. Equipment for such tests is illustrated and typical test results are given. Finally, some remarks are made concerning the basic mechanisms by which vibratory motion loosens bolts.
