Ive used this combination for panel attach and other mechanical holding and it may have application for some obscure radio application so I figured I'd share it. The Keystone 451 mini banana plug snaps into and snugly fits a 6-32 nut or standoff as shown.

I think 6-32 is way too small.

The maximum inside diameter of a #6-32 nut is 0.1495 inches (actually a tad more).

The expanded diameter of the plug blades is 0.120 inches.

Probably a #4-40 nut would work.

Trust me youll never get the banana plug into a 4-40 nut. The nut and standoff in the pic is 6-32 and the rear of the plug screws into the same threads so unless it shrunk when I turned it around its 6-32. The internal thread minor diameter of Class 2-B threads at 6-32 is 0.114" so the plug at 0.120" un-sprung is a friction fit when inserted.

I don't know what a Keystone 451 is, but I have short banana plugs that are standard size. There ain't no way you could get one inside a 6-32 nut. Maybe an 8-32 or 10-32, but I haven't tried.
