Britain's Hollie Arnold won her fourth consecutive F46 javelin world title as team-mate Jonathan Broom-Edwards won his first in the T64 high jump in Dubai.
Welsh 25-year-old Arnold threw 44.73m- a new championship record - to hold off the challenge from New Zealand's Holly Robinson, who broke Arnold's world record earlier this year.
After a nervy start, three-time world silver medallist Broom-Edwards finally got his hands on gold with a 2.02m jump.
Earlier, Kadeena Cox, Thomas Young and Jo Butterfield all won silver as Britain's medal rush continued.
The Paralympic silver medallist from Rio 2016, 31-year-old Broom-Edwards had three times been the bridesmaid on the world stage, but in Dubai that finally changed.
Clearing 2.02m with his final jump - some 13cm down on his personal best - he beat Uzbekistan's Temurbek Giyazov to gold.
"There are so many different emotions," he told BBC Sport. "Elated, relieved, proud, excited, a bit underwhelmed with my performance but I am happy.
"Eighteen months ago, I ruptured my Achilles so I've had to go through rehab to get myself back. In the six months leading up to this competition I then developed a knee condition which I was nursing and thankfully it held out today.
"It hasn't been easy, I didn't make it easy for myself but I did what I came here to do."
Reigning Paralympic, European and Commonwealth champion Arnold told BBC Sport: "Throwing a personal best and getting that fourth world title, it means so much to me after such an up and down year.
"To be able to go out there and just feel like old Hollie again, I can't wait for Tokyo now.
"I was upset [when she lost the world record in April] and I did have a little tear about it, but at the end of the day, world records are there to be broken but medals are there for keeps forever."
Cox and Young in silver success
Cox came into her T38 400m final as the defending champion from London 2017 but missed out a second successive world title as Russia's Margarita Goncharova set a new championship record of one minute 2.08 seconds.
Rio 2016 Paralympic champion Cox, who has multiple sclerosis, finished 0.12 seconds back after a late attack for the lead with a new season's best time.
"It's a hard one. It was so frustrating, just that last few steps," said the 28-year-old, competing at her first major championships since London 2017. "I think I knew I had it in there.
"It wasn't the type of race I wanted. I didn't execute my own race. Having everyone outside me meant I focused on their race and what they were doing. I think I judged my pace badly through the first 150m.
"I didn't go out hard enough and just didn't stick with them, which meant I had a lot of work to do around the top bend.
"I thought I had it in there, I know I can raise my game come championships. Some day, that was going to fail me and that day was today."
Moments after the completion of Cox's race, team-mate Young added a silver of his own to Britain's tally in the T38 100m final.
The 19-year-old had set a new European record in the heats but broke it again in winning silver in a photo finish, with Zhu Dening of China taking gold with exactly the same time of 11.00 secs.
"I came off the track thinking 'could I have it?'," he told BBC Sport. "I left it all out on the track.
"I've learnt a lot from this experience and taken it all in.
"I thought to myself on the line 'I've wanted to be an athlete all my life, I'm here now, so let's have the race of my life'. It didn't come off today but I'm really happy."
Butterfield wins first world medal since 2015
Butterfield threw a best effort of 21.67m as Ukraine's Zoia Ovsii won gold with a new club throw world record of 25.23m.
The 40-year-old won the world title in 2015 but finished fourth in London two years later after being plagued by a shoulder injury, yet she was still left wanting more in Dubai.
"It's a bit bittersweet, the distance wasn't what I wanted if I'm honest," Butterfield told BBC Sport.
"Tokyo is next year, the shoulder is rebuilt and we've got a lot of work to do to beat the Ukrainian, but there is still an opportunity.
"I'm back on the podium with a silver medal. Looking at the rankings, I was probably in third place so it's a bit of a bonus. There's a lot of work to do, but bring it on."
Rich Chiassaro missed out on the T54 1500m final but made amends in the T54 400m heats later in the day, finishing second in his heat to qualify for Tuesday's semi-finals.
There he will be joined by team-mate Nathan Maguire, who placed third in his heat to progress.
Great Britain finish day five on 15 medals.
