NON-REUSABLE LOCKING DEVICE AND METHOD OF USE ABSTRACT OF THE DISCLOSURE: A case hardened bolt is provided with a case hardened nut which can easily be hand threaded onto it. The shank of the bolt above a threaded portion of approximately the width of the bolt is of a reduced diameter such that the nut can turn freely with respect to the bolt. This portion of reduced dia- meter is at least as long as the width of the nut. In use, the bolt is passed through at least two hasps which are to be locked in position with respect to each other; the nut is threaded onto the bolt to have position in alignment with the portion of reduced diameter; and the threads on the bolt imme- diately adjacent the nut are deformed using a hammer and blunt chisel or the like, thus making it impossible for the nut to be removed from the bolt. When it is desired that the hasps be unlocked with respect to each other, the bolt is destroyed by using a bolt cutter on the shank, and the shank portions are removed from the hasps.
