Not sure about 5/16, but I don't think 1/4 will fit. I think that was the size I purchased at Rat-Shak (it was the largest they had) and it did not fit.

Ended up giving up and going the banana route.

AudioQuest UST banana don't fit either. I have some jumpers with narrow opening didn't fit so I just want to make sure. The binding post should be universal.
