Bury edged closer towards automatic promotion from League Two as a Tom Lees header saw off Lincoln at Gigg Lane.
Nick Ajose fired narrowly wide and Steven Schumacher's free-kick was deflected wide as the Shakers looked for an opener.
The Imps also went close when Shakers goalkeeper Cameron Belford did will to keep out Tom Kilbey.
Lees scored what proved to be the winner when he powerfully headed in a Peter Sweeney corner.
Bury caretaker manager Richie Barker told BBC Radio Manchester:
"It was harder today than my first day, as my first day had no pressure at all and the longer it goes on the harder it becomes.
"We've got those five out the way, I never dreamed we would get 15 points out of it and now have probably the three hardest games of the season.
"I thought he [Tom Lees] was brilliant today and man of the match by an absolute country mile."
Lincoln City manager Steve Tilson told BBC Lincolnshire:
"It was always going to be a tough game away at Bury, they're going for promotion and at home. It was almost a perfect away performance, but a lapse of concentration on one set-piece has cost us today.
"There weren't a lot of chances in the game at either end so I'm disappointed to come away with nothing.
"We played 4-5-1 as it tends to keep you in the game. We played 4-4-2 at home to Bury and we got so overstretched and they beat us 5-0 so there was no way we were going to come here playing 4-4-2 and get battered again. It worked for long periods but one corner has killed us."
