I bought a big picture hanging parts set at HD last night, just to get two of the mirror clamps -- HD did not have any in small packs. I will try adhering it with JB weld and see if it has enough shear resistance to stay in place when clamped. Rivets are a great idea over screws. If the JB Weld fails I may be adding a rivet gun to my toolbox.
