A nut for use in a bolt assembly having an adhesive anchoring capsule for attaching roof or wall supports to the rock structure of a mine. The nut has deformities in its continuous internal thread that cause the continuous internal thread to bulge inwardly toward the axis of the bore. The deformities limit the advance of the nut upon a bolt and are formed by stamping dimples into one face of the nut. When an overcoming torque is applied, the deformities in the continuous internal thread are pushed radially outwardly and the nut is allowed to further advance upon the bolt. Because the deformities do not form a break in the thread, which remains continuous, no fragments are formed to damage the bolting tool, and the bolt thread remains undamaged so that a second nut can be threaded on it to hold a screen or the like.
