A rock bolt anchor includes a top portion permanently fixed to a bottom portion. The top portion carries a package of resin. A spring-loaded mechanism pressurizes the package and forces the resin out when the package is lanced. The bottom portion main body carries a pair of opposed outer shells in a dovetail joint on opposed tapers. The annulus adjacent to the rock bolt anchor is sealed by top and bottom bulkheads. The bottom portion is threaded onto a rock bolt. A hollow and ported lance is threaded onto the exposed end of the rock bolt. The combination is inserted into a drilled hole and the rock bolt rotated. The lance rises and pierces the package releasing into the sealed annulus. Continued rotation of the rock bolt, forces the main body down and the outer shells up the tapers compressing them against the wall of the drilled hole.

A self-locking nut is formed with a rear nut body with internal threading and a front nut body having circumferentially arranged, crush-locking lips provided on a forward contact face of the front nut body and being spaced from the internal threading of the rear nut body by an internal relief cut for accommodating deformation of the crush-locking lips therein. When the nut is tightened down on an object on a fastener bolt, the crush-locking lips are forced inwardly and deformed on the threaded shaft of the fastener bolt into the space of the internal relief cut in order to form a permanent lock on the fastener bolt. In another preferred embodiment, the self-locking nut has a front “flying saucer” shaped part configured to work like a “jam nut” portion, and a rear “nut body” part having a front indentation space configured to work like an inner relief cut. The two parts are joined together by circumferential welding and flattening of the “flying saucer” part into the inner relief cut space of the “nut body” part while leaving a small gap between the parts.

A self-locking nut includes a main-nut body and a deformable-nut body. The main-nut body has a recess leading into an interior threaded bore forming x turns of an internal thread therein.
