Odessey terminals

[New2RS]

Afternoon all,
Picked up a used odessey pc680. I’ve removed the terminals as they were the wrong way round. One of the terminals had two washers under it which bridged the gap between the terminal base and the fixed brass nut which receives the allan bolt. The other had no washers so there was a gap.
So my question is- Are the washers necessary to prevent arcing or does the current travel through the bolt? (Which I assumed it would)
Any advice appreciated.

Never needed washers on either terminals in my experience.

as above, mine doesn't use washers at all, just the proper alan bolt terminal connectors supplied

Appreciated chaps.
I could see the logic but they seemed out of place so I’ll ditch em.
Cheers
