The Spireites had the better chances but the hosts deserved their point for their first-half performance and their overall work ethic.
The draw extends Town’s unbeaten run to five matches and the clean sheet is their fourth of the season.
Kabongo Tshimanga and Liam Mandeville had opportunities but Chesterfield did not create as much as what they would have liked.
Here are Liam Norcliffe’s player ratings from the game...
1. Scott Loach 7
A fourth clean sheet in five games. He made a couple of decent saves in the first-half. His stops after the break were fairly routine. Photo: Tina Jenner
2. Fraser Kerr 7
Made a welcome return to the defence after injury and was solid. Won his headers and tackles and cleared his lines well. Photo: Tina Jenner
3. Gavin Gunning 8
Chesterfield's man of the match by a country mile. Showed great leadership and nothing got past him. They needed more performances like his. Photo: Tina Jenner
4. Laurence Maguire 7
Battled hard and dug in. Came off in the last 20 minutes with an ankle injury. Photo: Tina Jenner
