If you have a stripped screw on your Ring Doorbell 2, you may be able to find replacement screws at a hardware store or online. It is essential to use the correct size and type of screws to ensure a secure hold and proper doorbell installation. If you cannot find replacement screws, you may need to remove the stripped screw and fill the hole with a wood filler or epoxy. Once the filler has dried, you can drill a new hole and install a new screw.
