JohanH: Yes, I already have the single banana pins with a thread on the other side. Just wondering, if there is a double one available.
jpanhalt: Hmm, that's an interesting find. Probably just what I was looking for - an enclosure for a custom current shunt resistor. It's obsolete and out-of-stock though.
ralphrmartin: Yeah, I know. I already have the individual threaded banana plugs, but the problem is that the tiny enclosure I'm using is made of aluminium, so, as you've already stated, it's a no-go.
The thing with these double banana plugs is that they're held together by plastic which also insulates them from the panel. It does require you to drill a bit larger holes though.
I'm looking for something to make a DIY current sense shunt that's small enough to be plugged directly into a benchtop DMM.
Something like this (although the enclosure seems 3D-printed):
