    Two of the terminals should be brass, for the black and red live wires.

    What is the make and model number of the plug you have?

    Did it come with any instructions?

    Why 10/3? Does your heater require a neutral?

    If the screws are all silver it tells me this could be a twist lock receptacle, but the three silver makes me wonder if you have the right one.
