- 1). Insert the tip of a jeweler's screwdriver into the tiny slot on the head of the temple arm hinge screw. A lug on the left- and right-hand edges of the eyeglass frame holds the arm hinges. Support the hinge on the edge of a table. Apply downward pressure to the head of the screw with the screwdriver and twist counterclockwise. When the screw is loose, lift it out with a pair of tweezers and put it to one side.
- 2). Insert the attaching lug at the end of the replacement temple arm between the two hinge brackets, the right way up. Line up the hinge and temple arm screw holes by inserting a needle into the screw orifice and moving it gently from side-to-side.
- 3). Attach the temple arm to the hinge with a new screw from the eyeglass repair kit. Support the hinge on the edge of the table. Tighten the screw by turning it clockwise with the jeweler's screwdriver until it starts to bind and then won't turn any farther.
- 4). Paint a dab of clear nail varnish onto the exposed end of the new temple arm screw and let it dry. The nail varnish will act as a thread seal, which will prevent the screw from working loose.
