I think I understand the problem. The original screws were hand formed by diaphanous Grecian nymphs and imported into Great Britain during the earlier part of this century under heavy cover. They have interesting resonant properties that uniquely conform to the (formerly) SAE thread orifice presented by the female mounting stub located at the four most folded corners of the laminated steel transformer shell. This explains your struggle.
Seriously, I have three pairs of ESls and 3 spare output transformers. I went to the extent of removing an original screw and used an ordinary 10-32 thread and it works...additionally, took the original screw and spun on an ordinary 10-32 nut and it works fabulously. Sooo you might have an odd ball or sometimes aligning the screw is a real pain: loosen the two that you have in there so that the tranformer almost flops and put a little silicone grease on the end of a 10-32 screw and it should work.. The studs the screws fit into are brazed on they may have been deformed in the original process or could have been damaged by a previous owner??? Try a brass screw as this is softer and will "conform" without doing further damage if you have to....I need to get a life...Good luck with it hope this helps!
