I like my anti tamper valves.

I would have said valve stems, but it doesn't apply as there is one stem for 4 valves.
Nice to know it makes it more of a pain for someone to screw with your valves and air.
These are Gorilla brand stemless valves which are subsurface mount and the case holds the stem and lugs key.
To check or add air the slotted cap is removed and the stem screws in.
