Alex Marshall and Paul Foster made it a golden double as they helped Scotland thrash England in the men's fours final, while Dan Purvis won gold in the men's parallel bars.
Purvis won gold after seeing off the challenge of England's triple gold medallist Max Whitlock.
The 23-year-old Scot produced a stunning routine which scored 15.533 to take the title ahead of England's Nile Wilson who won silver with 15.433, while floor, all-around and team champion Whitlock had to settle for bronze with 15.066.
Purvis, who had already won team silver and rings bronze, upgraded to gold on the final day of competition after being the last gymnast to perform on the apparatus.
In the bowling, Marshall and Foster teamed up with David Peacock and Neil Speirs to inflict a 16-8 victory in the Auld Enemy clash at Kelvingrove.
Marshall was cheered on by fans waving banners such as Tattie Marshall for First Minister and Tattie Marshall: the Lionel Messi of bowling.
Rather than the 'get it up ye' celebration witnessed after the Scots duo's victory in the men's pairs earlier in the week, all four men jumped in a huddle after they concluded their 16-8 win over their English rivals Andrew Knapper, John McGuinness, Stuart Airey, and Jamie Chestney with fully an end to spare.
It was the second final defeat of the day for England after Jamie-Lea Winch and Natalie Melmore lost 20-17 to South Africa in the women's pairs final, with Northern Ireland picking up bronze.
While Marshall helped steady the nerves in an end-to-end start, all four played a full part.
"It is unbelievable, a fantastic feeling, particularly to do it with such friendship," said Foster. "The way Neil and David have played throughout the tournament has been unbelievable."
Meanwhile, in boxing Reece McFadden took bronze in the 64kg light-welterweight division, while Josh Taylor will fight for gold after earning a unanimous points win over Sam Maxwell of England in the semi-finals at the Scottish Exhibition Centre in Glasgow.
The 23-year-old southpaw produced the more telling work in a close contest to win the first two rounds on all three judges' scorecards and, although losing the third, stayed sufficiently out of trouble as Maxwell went chasing a knockout.
Taylor won silver in Delhi four years ago and believes he can now go one better against Junias Jonas of Namibia, who defeated Sean Duffy of Northern Ireland, in Saturday night's match-up in front of an estimated 11,000 crowd at the SSE Hydro.
"I've never been in the Hydro before, but I have been in big venues," he said. "I boxed in front of 10,000 at the Olympics, but it might be different being a Scottish crowd, so I will try not to let that faze me.
"It's going to be amazing. I've been dreaming of this for God knows how long, certainly the past four years.
"The disappointments of the past have been and gone. I have just been looking forward since the last Commonwealths and the Olympics.
"I'm 100 per cent ready to win gold."
Reece McFadden went down to a split decision to Andrew Moloney of Australia in the last four of the flyweight division and launched an attack on corruption within the sport after feeling he had been robbed of a shot at gold.
"I thought I just nicked that last round as I was busier, but that's what happens in boxing," said McFadden. "It's corrupt.
"That fight wasn't a big robbery. He's a tough boy and it was a close fight, but I definitely think I did enough to get the decision.
"I said to his face that I thought the fight was mine and so did my coaches, but he worked hard for it and I've wished him well. I'm just scunnered not to make it to the final."
