After a bright start to their second northern venture in 10 days, the injury to Scott Quigley looked like it cost Wrexham dear, as they missed his presence up front.
There were still chances, Chris Holroyd and Shaun Pearson both hit the Gateshead woodwork, but it was an ultimately frustrating evening on Tyneside.
Dean Keates named the same starting line-up from Saturday, after James Jennings recovered from the early knock against Tranmere Rovers that forced him out of the action.
Wrexham started the game like a runaway train and created four chances in the opening three minutes, with Shaun Pearson seeing one header roll along the cross bar and Scott Boden watched on as his close-range effort was cleared off the line.
In the fifth minute, the ball wasn’t cleared from the Wrexham box and it fell to Gateshead’s Paddy McLaughlin, who spun on the spot six-yards out, but with the goal at his mercy shanked his effort well wide.
Scott Quigley showed his pace on the wing with 10 minutes on the clock and his ball into the near post was aimed at Paul Rutherford, but it took a good interception by Scott Barrow to avert the danger, even at the expense of a corner.
There was a booking for Barrow on 19 minutes, after he kicked out at Kevin Roberts, it seemed a totally unnecessary reaction form the local player.
The Heed responded with two quick efforts, that first saw Ben Fox have his effort blocked in the Wrexham box, before the ball rebounded out to Jordan Burrow and his low effort from 20-yards fizzed only inches passed Chris Dunn’s right-hand post.
There was a booking for James Jennings on 24 minutes, after he took down former Red Wes York.
Quigley went down on 29 minutes and after treatment on the pitch, headed for the sidelines to be replaced by Akil Wright shortly, afterwards.
Wrexham were back on the attack on 40 minutes, when Marcus Kelly crossed from on the left and it was Jamal Fyfield who was happy to head it away. Only for Rutherford to pick up the loose ball on the opposite flank, cross in to the centre for Wright to head downwards, but his effort was cleared from close to the home goal.
On half time, the home side were awarded a free kick 30-yards out and Barrow tried his luck from his distance, forcing Dunn into a hurried save to his left.
The opening period of the second half was quite a tame affair and it took until the hour mark when MacLaughlin’s low shot was cleared in a crowded box by Shaun Pearson, that either goal was even threatened.
Keates made a second sub on 66 minutes, when Jack Mackreth was sent on for Kelly.
A minute later and Newcastle United youngster Lewis McNall replaced Johnson for the Heed.
A long Jennings cross on 70 minutes, was headed down to Holroyd by Boden and his first-time effort was palmed away at full stretch by keeper Montgomery.
Pearson was on hand after 75 minutes to block a fierce drive by McLaughlin, as the home side enjoyed a period of pressure on the visitor’ goal.
Wrexham passed up the best chance of the game on 87 minutes, when Jennings whipped a diagonal cross into the box and Holroyd had a free header from six yards out, but only ended up striking the outside of the near post.
At the other end, Pearson headed a corner away, but on the follow up Ben Fox broke into the Wrexham box before firing his rising effort off target.
Despite two added minutes it was another clean sheet for the Reds, but the first in 14 for the Heed.
