I want to replace the M6 bolts that came with my batteries from China with SS and slightly longer.
The busbar is 1/4" thickness and I'm not convinced I'll need washers / lock-washers. I would however like for the head to be as large of surface area as possible. I don't know if that's even a variable.
The hole depth in the battery is 6mm. The busbar is appr 6.5mm. In order to bottom out a bolt against this busbar I need appr 12 - 13mm bolt thread length.
Then there's the thickness for the leads from the BMS terminals.
I have ZERO aspiration of going to any big box store and finding SS M6 bolts with this thread length.
So I'm asking all the rocket surgeons here for resources they know and trust to purchase more than qty = 70 pc.
THANKS in advance.
