Abstract
In the present research paper a detailed review on root causes and reasons which results in vibration loosening of bolted joints and fasteners has been carried out. Authors have reviewed the various research studies carried out by previous researchers in this particular area of research. Main reasons of loosening are vibrations incurred, cyclic loading and unloading of threaded nut-bolt assembly components. Many researchers have developed machine set ups for their experimental work. Loosening i.e. unlocking rotation of bolted assembly is mainly caused by the restoring action of an elastic torsion of a bolt shank because of the relative motion relative to its mating surface on threads. After review of literature it was concluded in this review that the most occurring root cause of loosening is side sliding of the nut or bolt head relative to the fastened joint, resulting in the relative motion occurring within the threads. If this does not occur or can be prevented, then the loosening of bolts can be reduced.

Key-Words / Index Term
