I quite like turret tags, or turret posts, whatever they are called.
Considered old fashioned nowadays, but easy to insert and place and
they allow air flow under and around the rectifiers. I even made a
little steel jig to enable accurate drilling when I make another.

Has anyone seen inside a rectifier "stick"? Are they just normal
rectifier diodes soldered together then epoxy encapsulated?
