I find a lenght of rubber tubing of the correct diameter is useful for inserting the new pugs and starting them off without the fear of cross threading. Push the tubing over the plug nipple,lower the plug into the aperture then twist the tubing to start the threads,once started simply pull off the tubing and tighten to the correct torque with the plug socket.
I always start by turning anything threaded the opposite way, and feeling for the slight click as the thread locates, before switching direction to tighten.
