This is the most secure way of hang pictures. Screw the 'T-Headed' screws into the solid/brickwall. Attached the small metal brackets onto the back of the picture frame. Each bracket has a slotted hole, with which the T-Headed screws slot into. To secure the picture, simply rotate the T-Headed screw 90 degrees.
