Gregor Tait ensured Scotland collected three swimming golds for the first time in Commonwealth Games history as he won the 200m backstroke final on Saturday.
Tait celebrates his superb victory
It follows Caitlin McClatchey's win in the 200m freestyle and David Carry's gold in the 400m freestyle.
England then sealed a one-two in the 100m breaststroke - with gold for Chris Cook and silver for James Gibson.
And England added victory in the 4x200 freestyle relay with Scotland runners-up and Australia third.
Tait won in a new Games record of time of 1:58.65, beating South Africa's Johannes Du Rand and New Zealand's Cameron Gibson.
"It was a just a case of doing my thing, I didn't have to worry about anyone else, just myself," Tait said.
"This is the strongest team we've had for a long, long time and we are proving it."
Cook, who had been the fastest qualifier for the 100m breaststroke final, was down in fourth place at the turn.
But he produced a superb second 50m to beat team-mate Gibson on the final stroke.
The 26-year-old from South Shields clocked a time of 1:00.98, inches ahead of former world champion Gibson in 1:01.10.
Australia's Brenton Rickard prevented an English clean sweep with the bronze, just ahead of Darren Mew. Scotland's Kristopher Gilchrist was eighth.
Cook revealed that he tried to take the pressure off himself before the race.
"I was so focused out there that I wasn't even thinking I was in the final," he told BBC Sport.
"Eighteen months ago I was thinking of packing it in as I was out of form, but here I am and it's just awesome."
Cook's team-mate Gibson also hailed his return to form with his silver medal.
"For me, it's been a couple of tough years.
"I've been off the podium for a while but now I'm back up there. Hopefully there is still more to come."
World champion Roland Schoeman, already struggling with a sore shoulder, shrugged off a cold to win the men's 50m butterfly title in 23.34, adding to his gold in the 4x100m freestyle.
England's Matthew Clay was unable to add to his 50m backstroke gold when he finished seventh, one place behind Scotland's Todd Cooper.
In the 4x200m relay, Simon Burnett gave England's quartet the perfect start.
But after Alexander Scotcher and Dean Milwain were unable to hold on to the lead, individual champion Ross Davenport took over several metres behind Australia and Scotland.
And the 21-year-old, from Derby, timed his charge to perfection to overhaul Robert Renwick in the final few metres.
"Australia have been the masters of this event for many, many years," Davenport said.
"They were a weakened team without Ian Thorpe and Grant Hackett, but it doesn't matter.
"On that medal it doesn't say Australia minus two, it just says Australia and we beat them today."
