Negative ground for air compressor?

[Bftx]

Is the raised bolt in the image (to the left of the hood strut in the image) the designated spot to hook up a ground/negative to when using an air compressor?

I’ve never heard of using a ground on a vehicle to use an air compressor.......

It’s a good negative chassis ground. It’s there for jumpstarting purposes. You can use it to ground a portable compressor if you want or just use the battery terminals.

That bolt is for use with jumper cables, so yes, it would work for a clip on 12V air compressor.
