ABSTRACT:
An assembly of a bolt, a washer, a nut and locking structure for locking the bolt against rotation after the bolt, washer and nut have locked together a pair of flat, plate-like members in frictional engagement with each other. Any tendency for the bolt to rotate in a reverse direction will be prevented by the locking means. The plate members will essentially be bonded together against movement relative to each other, thereby maintaining structural integrity of the assembly. In a first embodiment, the head of the bolt has a notch for receiving one end of split ring washer. The other end of the washer is in a notch in the nut. The nut and washer define a locking unit for preventing reverse rotation of the bolt after the head of the bolt has been moved into proximity with the washer and the washer has been moved into the notch of the nut. Other embodiments are disclosed.
