Match ends, Alfreton Town 0, Lincoln City 0.
Alfreton extended their advantage over 21st-placed Welling to four points after a goalless draw with Lincoln.
The visitors, who drop to 13th, had the better of a poor first half but Jordan Burrow was not able to head Jordan Cranston's excellent cross on target.
Ben Tomlinson curled an effort wide before Alfreton's Jason Mooney saved well from John Marsden after the break.
Burrow, Marsden and Tomlinson all went close again for Lincoln, but the hosts held on to earn a valuable point.
Alfreton Town manager Nicky Law:
"I am disappointed not to have won it. It was a tough competitive game as you would expect, but I think we had the better chances.
"They have had a couple of long-range efforts but nothing to really worry about. We have had three good chances which fell to the person you would want them to fall to (Tom Shaw), but on this occasion he hasn't been able to take advantage.
"Overall, the team has worked hard defensively and 400 minutes without conceding at any level is good but we have got to continue to do that."
