Marlin 1895 Dark 45-70

Recently got my Marlin dark in 45-70, when I went to install the hammer spur extension I noticed set screw was actually missing from the package. I can not seem to find a answer as to what size and thread pitch this set screw is? Hoping for answer so I can maybe find one at a hardware store or order one off amazon or something.

Thanks
