    I'm looking to buy some bolts for my m/bike.
    the type I'm looking for is hexagon but with a dome like top.
    is there a correct name for them or is this m/bike manufacturers own thing?

    They are called acorn nuts, as well as other names. Domed is another one.

    Are these "load bearing" ? If decorative then what about simply using threaded rod with the nut to create bolts ?

    Just bought one, it was for the clamp holding the handlebars onto the headstock on a Suzuki quad. I had to go genuine Suzuki, and it was over £3, but at least will match the other 3 bolts. Spares for old Japanese stuff is often available for a long time, could be worth trying OE suppliers.

    In my experience, the bolts are made to order. There were a lot of bolts with profiled heads used by the British bike industry, ordered in their 10s if not 100s of thousands.
