"It was a tough competition. But I dug deep. I'm just speechless. It's surreal, it hasn't sunk in yet," said Davies.
"I knew what kind of form I was in and that I'm good shape but you still have to do it on the day.
"Four years of hard work for this - it's nice to give something back to everyone. I'm just so happy I performed. I've worked so hard so to deliver, and to give something back on the biggest stage, I can't believe it."
"It's sad to know that was my last event. This place is addictive. I've got a lot of love for this crowd. Everyone was in tears at the end - it made me cry.
"I was going head-to-head with the Iranian guy who I've been in competition with for some time. He threw well in the first round and I thought 'I can do better than that'. And then I threw better."
Elsewhere, Stef Reid took the silver medal in the F42/44 long jump. She broke the Paralympic record with a 5.28m leap but Kelly Cartwright then claimed the world record to pip to the British athlete to gold.
Paralympic long jump competitions sees athletes from different disability groups combined with their distance converted into a score - and Cartwright's winning margin was just seven points.
"I’m so happy but those few points are killing me, it’s so annoying," said Reid.
"I’m gutted but I’m thrilled at the same time. It’s quite controversial and disappointing they chose to combine the categories but Kelly is a great competitor and jumped amazingly and she deserves it.”
