Both teams hit the woodwork but it is United's defence who will be hailed after producing a solid performance for 90 minutes.
The sides will play their reverse fixture in a week's time, but the next game cannot come quickly enough for Neil McNamara, whose side has the opportunity to leapfrog relegation rivals Andover New Street to climb off the bottom of the table.
The Humbugs play Andover New Street away at 3pm on Saturday.
