The security screws are two tiny black screws in a long black channel that no one can see to insert a Phillips screwdriver into the screw heads. I managed to attach a security screw using tape to secure the screw head to the screwdriver. The tape held it in place so I could screw it in. My mistake was not buying another long screwdriver and attaching it to the screw at the same time and then having someone screw it in while I installed my side. I wanted to add a security screw because I installed a TV mount and my new wall has huge screw holes. Do not buy this TV mount.
