I have restored some 1940's pine windows. When I removed the original screws, the screw holes were filled with eggs from 80 years of use. Another attempt to fix the screw holes. They work. Easy and uncomplicated. They are easy to use; Just screw them into the hole, snap them off and put the screw back in. Ready! I kept the rest of the broken part in case other large holes were found that needed repairing. If you have bad loops, please feel free to buy them.
