You’ll be gluing these screws in place with a mixture of baking soda and crazy glue. This stuff hardens real quick and a lot of people use it for quick repairs and filling in tiny holes in stuff. Place the screw in the hole and add a little bit of crazy glue. Next add a little bit of baking soda and with your finger squeeze and compact the baking soda into the hole. The mixture should harden almost instantly. Blow the excess powder out and repeat the process until the pocket is filled. If you overfill, don’t worry, file the rest of the excess off so that the mixture is even with the actual ear surface.
