Awning window screw

Looking at your photos, it appears that the screw you're looking for is a #10 diameter screw and 5/8" long. We carry the 33-081, which is a #10 screw at 1/2" long. We use it to secure the Awning window casing to the window. We like it because it has a "blunt" point and is less likely to interfere with the operation of the window linkage and gear. What do you think?
