If checkbox value is to be set on document ready:

$(document).ready(function(){
    $(".checkboxclass:not(:checked)").val("10");
});

If checkbox value is to be set on checkbox click:

$(".checkboxclass").click(function(){
    if(!$(this).is(":checked")) {
        $(this).val("10");
    }
    else {
        //do something
    }
});
