What are stove bolts? Stove bolts are sometimes referred to as machine screws as they have a machine thread and round head. Fastener Solution’s stove head bolts come with hex nuts and are available in zinc-plated steel. When purchasing stove bolts and nuts, remember to purchase flat or fender washers as washers are typically needed in many stove bolt applications.
