That being said, the more COTS teams are in 1/4-20 land. This makes sense.

Being Mr #10, I'm STOKED about the hole as we'd never use a bolt to retain the items on a shaft... but these will make great heavy duty standoffs with the hole already drilled.

ThunderHex is my favorite new product, and I think they did it perfectly. Now time for 3/8" thunderhex next year

I'm curious as to why you'd never use a bolt to retain items on the end of a shaft? A big reason is that it is easier to get students competent in using a bolt and Allen wrench that using snap rings and e-clips. It is also easier to get students competent in tapping the end of a shaft than cutting a groove for an e-clip or snap ring on the lathe. I don't like shaft collars because they are more expensive to purchase and add length/width that you don't need with a bolt in the end.

I'm also not a big fan of the though hole for stand offs and prefer a bolt in each end. If you have to remove what ever the stand off is holding you often just need to remove one side. So if one side is still bolted then you just place the removed piece back on and bolt it on. With a through bolt the stand offs are then loose and you have to put align them all when putting it back in place and you need two tools to reassemble. Yes during initial assembly you'll need two tools but in repairs during the heat of competition putting a bolt back in one side is quicker.
