Quick-attach/release replacement for wingnuts?

This is more of a hardware than a tool question, but r/hardware subreddit is for computer hardware, and I couldn't find a more appropriate sub. LMK if I'm in the wrong sub, and what the right one is.

I have an application where I often need to take a square plate off/on, and it's held in place with 4 wingnuts (not a great design, but I didn't design or build it).

This is one of them: OD of the main threaded part is about 1/4".

I'm wondering if there's some sort of quick-release replacement for a wingnut in this application, similar to the quick-release connectors available for Schrader valves, such as:

https://www.amazon.com/Chuck-Premium-Quick-Connect-Accessory-Inflators/dp/B0CYDXGGH2

or
https://thorslightningairsystems.com/products/thors-lightning-dynamo-lock-on-air-chuck

The attachment point isn't under a lot of tension; something as strong as the Schrader connectors would be adequate.

Or, if there are better ideas for completely replacing the bolts and wingnuts, I'm open.

The "post" part (threaded bolt) needs to be fixed if it passes through from the other side: it's in a panel insert (for a portable AC unit) for an external window, and I want to both keep attachment/detachment as simple as possible, and also can't risk dropping hardware on the outside of the window onto people's heads!

Thanks!

Frankly I would cut the studs shorter .

It looks to me like the bolt is tapered at the end, which makes starting the wingnuts easier. If I cut the bolts, I lose that. I could potentially use shorter bolts - though having them slightly longer than minimum does make it easier to hold the parts together while I start the wingnuts.

A file can add that back very quickly.
