Should read just one of many sources.

That’s because it’s a spline. Not hex, not torx.
Spline AKA Bristol.

Collins always used them on knobs and set screws.

Subject: [Amps] Plate hardware for Eimac tubes
Hi - having some difficulty here swapping tubes around. Is there a standard
tool/hardware size for the plate caps and heat sinks on top of the Eimac
tubes (I'm working with 3-500s and 4-400s this evening trying to get an amp
working). It seems like it must be a Torx T5. Is that right? Is it
standard? Hex keys don't seem to work, and the set screw heads are so small
I really can't see them well enough to get after it without risking damaging
tool or part. (Also I don't have a Torx T5 and it just seems like that must
be it but I don't have one to try).
Help? Thanks.
