Universal radiator valve caps don't fit

The universal radiator valve caps I bought don't fit, there is no slot like a flat head screw inside...what caps do I need?

Not one we can answer here, I would think. Too much variation in valve heads, etc. Even a plumber's would struggle there.

Wow, I did not know that.

Thats not a great picture but after a quick look on Amazon I wonder if these would have the right adapter?

What you have are also known as lockshield valve covers or valve covers for the valve you do not adjust on your radiator. You need are either these below if you have no idea what valves you have,

otherwise pull off on good valve cover from another valve and bring it to a plumbing suppliers / proper hardware shop and ask at the counter for as many as you need of the type in your hand.
