LEAVE the FRIDGE ALONE!
Gotta give this person props for the ingenuity, but in general, folks who disassemble a refrigerator for the hardware to install a rack or fenders or something are DOING IT WRONG! Establish a relationship with your local hardware store. Any hardware store worth its salt has an extensive stock of metric cap bolts, aircraft nuts, and other quality fastenerisms. And LEAVE YOUR FRIDGE ALONE!
