For AC/DC radios especially, where the threads required are a little coarser than an ordinary bolt, does anyone know what type of bolt available today from a hardware store, would work as a replacement?

Hi

Different types of blots were used. Some used sheet metal screws. Most were shaped like machine screws but with threads similar to wood screws. If you have one take it to a hardware store. They will be able to match it.
