What size screws are needed for Swisco Window Sash Lift, 3-1/4", Product Code: 26-174.
I intend to use machine screws through the window with washers and nuts on the outside.

Thanks for posting! We suggest using a #8 screw to install these. You'll need to use you discernment on the length you'll need based on the installation process.
