It's from a Stelrad radiator of about 20 years ago. I have the same problem and wasn't able to get replacements. I still could do with some if anyone knows a source. Had to chuck away two rads perfectly good except for the bleed screws.

They have a full range of replacement bleed screws for: Cast Iron Radiators Panel Radiators Myson Radiators
You can also sell a selection kit which you can buy and return for a refund if you are not sure which bleed screw you require.
Worth taking a look before getting rid of the old radiator

Just use any old hex. brass bolt. Put a point on it with file /grinder. If it leaks a bit, use some PTFE tape.
Very odd would not one think that such a screw would just be, um, a screw with the normal thread? Brian
He's probably either sorted it out or got rid of it in the last 6 years.

A normal screw won't create a water-tight seal when closed. Bleed screws have some mechanism for generating a seal (often a cone seal on the tip).
I wouldn't use them. Apparently they're appallingly slow at responding to questions.
