Security bolt, if it has a bolt coming out of it or a hole for one.

Looks to me like you're too young to know the first thing about those dimple
washers that come with inner tubes that have metal valve stems.
The dimple washer and one nut goes * inside* the wheel.
The other nut goes *outside* the wheel.
This assemply sequence *centers* the valve stem in the hole and prevents the
valve stem from being pulled out of the inner tube.

Well, that's what it is, nonetheless. It'\s a security bolt, and that's
the reason for its fitment.
However, yes, you're technically right. It's designed to stop the *tyre*
moving on the rim and dragging the tube and valve with it, rather than
the tube alone.

Sorry, it's not designed to stop the tyre from creeping, or even the
tire.

No, you're right. His original pic showed the valve separate from the
tube, as an independent piece, and so it looks like a security bolt.
