Unidentified Electronic Part

I have a (dismantled) IR remote controller for a drone, and the board has a component that I have never seen before. Anyone know what it is? https://imgur.com/a/mNgYT9l

It seems to be a component to be connected, eventually, to a heat sink, tightly, with a screw. There is maybe some info printed on the board, under the component.
