No, its not wrong or anything. I prefer not to since the relays are plastic and you can't tighten the bolts down as much as I'd like. But since its the ground for the relay, its not a high current load, so it isn't as big of a deal.

generally, no. But remember, most screws (to mount the relay) are not going to give you a great contact. If you use 2 flat washers and a small bolt, that should work.

well, i am using a bolt, not a screw. but if i understand what you're saying, i should add a washer in between the back of the relay and the ground wire?

Just scuff the paint off at the mounting point and it'll ground...
You don't need a washer...

I have used the relays with the metal mounting brackets like that many o time...
The plastic mounts can crack if overtightened... But I think you can get them tight enough to allow the ground without cracking them...

Unless yer just one of those hamfisted individuals... ;)

If corrosion may be an issue where you live, then a star washer between the body and lug would give longer electrical reliability. As long as you can tighten the bolt down enough.
