Several embodiments of reactive biasing fasteners utilized in place of jam nuts and Belleville washers, providing for the storage of a pre-load and effectively providing a locking function to prevent unintended loosening of an associated bolt. The embodiments resiliently deform under load to store pre-load or live load energy. Further, the fasteners are adapted to interface with a self-reacting tightening power tool-thereby eliminating or minimizing the need for backup or secondary wrenches. Additionally, several embodiments, through the incorporation of a threaded bore, effectively act to minimize side loading on the portion of a bolt located in the bolt hole of a workpiece when in use. The resilient deformation of the biasing fasteners permits the live load to be stored therein. Accordingly, the risk of loosening of the bolted joint due to exteriorly applied forces such as, but not limited to, vibration and thermal expansion and contraction, is lessened.
