Our previous studies have shown that even under repetition of very small slip at bearing surfaces of bolt nut joints loosening rotation can occur and grow larger. This report presents experimental considerations about external work consumed at bolt-nut joints during repetition of transverse loading and locking performance of a "double-nut" (a nut with a lock nut). The consumed work and its changing state have various patterns in response to properties of test samples. It is considered that its quantity and behavior express features of locking properties of the samples. It is concluded that the locking performance of a double-nut is very doubtful except cases when locking operation is correctly completed.
