It’s a drum key. Specifically, it’s this drum key. Technically, it’s the same size as a 1/4″ water key, but this particular one is sold and marketed to drummers.

Someone said:

It’s a key for turning things with a square head, such as water valves, gas valves, etc

Someone said:

Drum key. I’ve lost so many of those over the course of my life.

Someone said:

Either a drum key like others have mentioned, or a tuning wrench for certain instruments such as a hammered dulcimer or bowed psaltry

Someone said:

Back when I used play the drums in various bands when I was younger I kept one on my key ring

Someone said:
That’s a drum key, it’s used to tighten the screws on drum head to change the pitch.

Someone said:
That’s a square/drum key. They are commonly used in technical locks where whatever hidden isn’t as important to require a unique, separate own key. For example in railways it’s the most common type of lock being Found nearly everywhere; on the battery hatches, on door locks and manual pneumatic door openers, on maintenance hatches which hide all the electrical or pneumatic stuff away from passengers’ reach etc.

Someone said:

I once tried to use a drum key to wedge a plug out of an outlet. Seconds later the wall was black, I was a few feet away and half the t part of the key was missing.

Someone said:

Gas key for a gas fireplace insert. Look around on the floor near the fireplace, there’s probably a semi hidden place to fit it.

My house has this, but the gas insert was removed decades ago (for obvious safety reasons). But the key is still sitting on the mantle.

Someone said:
That’s for like sinks in public restrooms where you can’t have a valve cause someone will turn it on lol

Someone said:
Water key … used at like every school in the great US of A … for outside spigot

Someone said:

It could be a key used to turn the gas valve on for a natural gas fireplace

Someone said:
the hole looks a little large to be a radiator key, so probably a drum key
