Hello, I believe you are referring to the screw "bosses". Their purpose is to keep the screws lined up when installing the handles. You might need to make the holes in the patio door a bit larger to accept the 82-036 screw bosses. You might be able to use a rat tail file or drill the holes larger. I believe that this should replace your original handle set with a little retrofitting. Alternate image for 82-036
