Johnny B Good:
 Thanks for settling the matter in regard of my answering the wrong question. :) :-[

 Hopefully, my edited version has provided the answer to the actual question you had been asking.

 Your nicely pragmatic solution is a neat way to solve the problem using the bits you already have to hand. Some might regard it as 'a bit of a bodge' but to my mind, its more a case of 'inventive lateral thinking'. ;)

 I've tried similar repurposing of these lugs (as I'm pretty sure most eevblog members will also have done) but with rather mixed results, mainly it has to be said, because the lugs I'd used were not as good a quality as yours.

 I suspect others have hit the same problem and would have needed to spend time and money to acquire a stock of decent quality lugs to emulate your solution, hence the interest in spending the time and money instead on these 6M binding post kits just for the 4mm banana socket adapter lug nuts.

 My post about my experience in purchasing a set of these M6 binding posts had been to provide a "Heads up" for anyone else contemplating this 4mm banana socket adapter exercise over the risk of landing up with M6 fine threaded binding post nuts which don't fit on the SDL 1000X terminal binding posts.

 BTW, I fully understand Siglent's decision not to curse these electronic loads with 4mm banana jacks since apart from the complaints about the lack of high current rated binding posts, this could also lead to a higher rate of expensive shorting out accidents with power supplies and battery packs. Far better for Siglent to leave the choice of potentially unsafe connections entirely in the hands of their customers than to be seen to be encouraging such misuse of banana plug ended test leads.

 A better solution to arranging a more convenient connection IMHO, would be a pair of 4mm banana jack plugs attached via a couple of 3 or 4 inch 10 gauge flexible lug ended fly leads  and use test leads terminated with solderable in line banana sockets. Basically the same connection method you'd use to test wallwarts with co-axial dc plug ended flyleads.

The knobs and washers off the "new" posts are just threaded onto the Siglent binding posts after the original equipment knobs are removed.

... is what I believe most of us have been doing with those banana posts adapters.

Just unscrew the exiting knobs from Siglent, and from the new ones, insert a washer and screw the new knobs with the banana inserts.
One washer is needed because without it the new knob will not be properly tighten. "Disregard" the remaining parts.

This method will fit the purpose, and there's no need for any real mod of the Load.
It can be easily undone and the original knobs refited if a beefier cable with proper terminals is to be used, instead of banana plugs.

Thanks all, we'll likely order these next time we order something.

Nice to know no mods are required to E Load!!

This is the approach I've taken, as it seems like best of both worlds having both types of connections in place. Got Clough42's PCB and the Pomona banana jacks from DigiKey, just haven't assembled it yet. A project for the weekend maybe, if I don't get to it sooner.

Nice to know there's a simple mod with replacing the knobs with banana jack sockets if I need a backup solution.

 I have to agree with colorado.rob's assessment on this one https://www.eevblog.com/forum/testgear/siglent-sdl1000xsdl1000x-e-electronic-load/msg5078467/#msg5078467

 However, I don't agree with his suggested alternative solution https://www.amazon.com/gp/product/B08R2KJ88S?th=1 since neither of these solutions offers any more safety regarding the risk of shorting out of the DUT (particularly when the DUT happens to be an unprotected LiPo battery pack) than the 4mm banana socket adapter M6 binding post nuts which at least have the charm of being a neater and far cheaper again option than those audiophool priced spade tag to 4mm banana socket adapters.

 I guess anyone familiar with such LiPo battery packs would be well aware of the risks associated with them and always remember to disconnect at the battery pack end first before pulling the banana plugs out at the electronic load end (and likewise switch off an expensive mains powered PSU or shut off the bench supply feeding a dc-dc converter module), making the shorting out risk of the banana plugs a more acceptable one.

 The other useful feature of a banana plug connection as far as anyone testing LiPo battery packs is concerned being that they provide a method of swift disconnection to allow a flaming LiPo in its fire-bucket of sand to be swiftly ejected off the premises without having to sacrifice the electronic load as well (although keeping a suitable pair of side cutters to hand would serve just as well with the standard spade tag connection).

 There might have been some merit in that fancy adapter if it had used banana plugs instead of sockets so that the test leads could be terminated with in-line female banana sockets instead to eliminate the risk of an accidental short on the output from the DUT.

 If you're happy to accept the shorting out risk, the swap out of the binding post nuts with the 4mm banana socketed binding post nuts supplied with these M6 binding post kits represents the neatest and cheapest solution IMO.
