    In case anyone needs one.

    5mm shaft diameter
    6mm shaft length
    8mm head diameter
    3mm head height
    slotted cheese head screw
    .80 pitch coarse thread
    total length 9mm

    Therefore:

    M5-.8x6

    I found some on ePrey. They were not cheese heads, but philips pan head. Works fine.

    Was that screw originally brass or steel? Did it use a washer too? Looking at stoves for sale and was wondering what is original.

    Mine is steel, no washer. I have no idea what was original.

    Guys,

    I have six of those little gems, five that I can find, and one that's tucked away in a tub. Of the five, four had a steel screw, no washer, and one had a small steel screw, with a washer. That last one was a gift from a friend, and I think that the gifted 99 had a replacement screw, and not the original one.
