4-Wire Low Thermal Shorting Plug this is essential accessory for all bench-top multimeter of our times.

Fluke 884X-SHORT (product design) and also Keithley 8610 & 8620 they seem to chronologically exist since 90s.
I did explore both products specification and only Keithley this mention less than 1mOhm as resistance characterization between the pair of sense banana plugs.

Fluke 884X-SHORT compared to Keithley 8610, this seems better implemented due the existence of this basic pull-cord which every electrician he is familiar of this material  :)   

From the other hand this Keithley 8620 which is a Shorting Plug in to a cube, this seems as better choice if you do allot of work with this plug and you expect sorter times so Thermoelectric Voltages to be removed (zeroed down) .


In the DIY world there is allot of creative imagination, replication of such sorting plug design this is not impossible but rather difficult.
Low-end banana stud or plugs with fake gold platting they are everywhere.
50A gold plated banana stud they come only with the specification of 0.3 mOhm contacts resistance, this is the resistance when a male plug this gets in touch with an female plug.
Total length resistance this is unspecified. 
   
ITTSB Blog this now armed with HIOKI RM3542A , this is the best weapon for such materials resistance characterization.
I have in mind making some experiments in the future, it looks like that ITTSB Blog it is very close to engage with bench-top multimeter reviews.  ;)
