340 Negative Battery Bolt size

[Tim Murphy]

Crazy question but does anyone know the stock bolt size for the negative ground cable to the block? Looking for hex head size and thread. Can't go to the hard ware store since mine is closed due to Covid.
Thanks in advance!

It's 3/8 X 18 X 5/8 long. Shame on you if you don't have buckets of spare bolts. I believe it bolts to the head.

Keep meaning to sort mine out but never do

Don't feel bad, I have cans of bolts but never the right size.
