LINNETS' maiden clean sheet of the season coincided with a first-time failure to score as they ended the hosts' 100% home record in Vodkat League Division One.
Gate had hit seven goals while conceding only one in winning their first three at School Road, yet Linnets must still be wondering how they failed to register a first win on their travels.
They did everything but score in a match Steve Carragher's side dominated from start to finish - despite being without two of their most influential players.
Winger Michael Young, having only returned from injury in midweek, served a one-match ban after his openingday dismissal while skipper Paul Scott missed a second successive match for personal reasons.
In their absence, Linnets turned in a solid all-round dis-play but couldn't quite finish it off.
Although there was always the worry one mistake might cost Runcorn, they turned their defensive fortunes around.
For the vast majority of the game, Runcorn were the only team showing any attacking intentions.
But they still needed a vital recovery tackle from Neil Roberts and survived a late penalty appeal for handball to return home with the scant reward of a point.
The first half had seen them denied a spot-kick of their own when Tommy Boden was pulled back by the shirt.
Stand-in skipper Colin Flood led Runcorn's forward march down the left flank - in front of utility man Dave Standley, who again looked very accomplished at full-back.
Liam Loughlin forced a save from keeper Ryan Yeomans after just seven minutes - Thomas Lamb having touched on Flood's drag back.
That was just the start of the frustration for Runcorn with Lamb and Dave Thompson also missing chances to send them in ahead.
The only real fright in the first half for Runcorn came in the 28th minute when Michael Bird - leading the line for a very tall home side - screwed wide on the turn.
With a fresh crossfield breeze, the pattern was unchanged in the second half. But two more near misses in the last quarter suggested Linnets were destined not to find the net.
Thompson had already headed a perfect Jay Edwards cross over the bar by the time he was released by Lamb into the box in the 72nd minute.
The striker clipped the ball past the oncoming keeper but also agonisingly wide of the left upright, when it seemed he had finally broken the deadlock.
Then, 13 minutes from time, Lamb's skimming header from Flood's free-kick looked to be going in but the wind took it against the right upright.
Unlucky as Runcorn will feel, Squires Gate's big and rugged defence take credit as not many sides would have withstood such pressure.
