Vandal proof system for securing a frangible facing plate to rigid supporting structure by wedging action and a method therefor

摘要

Stone faceplates are secured to supporting structures in columbariums or similar environments by a non-standard star screwdriver which penetrates the exposed face of the faceplate to activate a fastening assembly having a rivet nut and screw which secures the faceplate to the supporting structure, the tightening pressure of the rivet nut screw forcing the prongs of a slotted spacer sleeve of the fastening assembly into jamming engagement with a hole in the rear of the faceplate.
