A quick glance suggests that these might be the same size as the R1155 RF/Osc coils, Not sure about the R1155 IF's. I might try and grind a slight taper on the bolt as a lead in and cut four opposing slots ie: rudimentary tap, a proper tap would be ideal I guess.
Hope this is of some use.

Sizing Sounds more like British Standard Whitworth rather than BA0, BSW7/16inch
