[Elecraft] Elecraft Digest, Vol 204, Issue 6

You may want to verify whether Elecraft specifies Thermal Material where the transistors attach.

My K3 and K3s both do. Haven’t disassembled my KX2.

Asked about that and the seller said he tried to put some sort of protective end plates onto the radio but couldn’t do it so threw them away and put the original end plates back on.  What concerns me about just going to the hardware store and getting more screws (that might not be the proper thread/length) is I think two of the screws held the final output transistors onto that end plate which I assume was for that end plate to act as a heatsink.

Sounds like the seller was a sucker for aftermarket stuff. Elecraft
products are well designed. The screws are all standard English units.
Most of are 4-40, smaller ones are 2-56.

I've NEVER thrown away screws -- I probably have close to a thousand,
sorted into plastic drawers by size. Ditto for lots of other mechanical
and electronic parts.
