Service nipple bonding

[Electromatic]

This should be straightforward, but I always second-guess myself as to whether I'm doing too much or too little....

I have meter base with a threaded hub on top. I plan to use a rigid nipple between it and the service disconnect fused switch above it.

Do I:
1) need to use a sealing locknut where the nipple threads into the meter hub
2) The disconnect has eccentric knockouts. Are regular locknuts okay since the nipple is bonded via the threaded meter hub, or do I need some kind of bonding locknut at the ?

Thanks as always

If you use a meter can with a bonded neutral you don't need any extra bonding for the the nipple as the hub connection complies with 250.92. The service disco. will have a main bonding jumper so that takes care of the enclosure bonding.
