Yeah! Machinists will still ask me if it's right hand to this day if it's not specified on the drawing. And customary, it is considered right hand unless otherwise specified. I always put 'RH' or 'LH' on the thread callout on the drawings I do. That way, it takes the doubt out of the equation.Anyone that works in a machine shop will assume that a thread call out on a drawing unless specified otherwise is RH as 4gsr found out.
