I agree with Stamcom, That looks like some sort of emt fitting that has been cut off. Definitly something with a larger base fed through the hole and maybe fastened to the conduit somehow. Give the guy some points for creativity.
Keep a pair of flush cutting 4" side cutters in the bag just for tywraps. No sharp edges when you trim the tail, and you can cut them off without knicking wires. When I was in the airplane wiring business, we went through ty's by the gross.

Thanks tx,
Now it all makes sense.
BTW, I've gouged my arm on sharp ty-rap edges many times. The small flush cutting dykes do work nicely.

If you use your side cutters to twist the excess tie wrap off instead of cutting it,it will not leave a sharp edge.

it's hard to tell if it's a connector or a nipple,if it's a nipple they cut it to short and just made it into the box and put the locknut on. but no bushing. i like the key
i also like the plastic connector for the grounding conductor.thats approved for grounding.right

Stamcon, TW;
If the galvanized disk is the shoulder flange of a conduit connector, isn't what we're looking at in the photo wider than the usual flange? Also, I see a notch in the outer edge of the flange at 2 o'clock, and what might be another notch at 10 o'clock.
This puts me in mind of a stamped steel nut with a single thread. If this is the case, I see no evidence of paint removal to ensure a good bond.

Some additional info: This was a electrical inspection to retap a new service at a residence, the issue - is there a good ground path? (equipment bonding another question) there is no doubt 110.3b is a violation as this is not a listed and approved fitting.

Pearlfish "Those square Nylon thingys with the double face tape on them are guaranteed to fall off in a week." Boy Howdy, P-fish ! Those stickyback things are awful. Not to hawk Panduit so much, but if you ever need some that will last, try EMS-A-CO bases with epoxy glue in place of tape.

How does using a cable tie affect heat disbursal from the conductors? In other words, do you need to derate to create bundles of conductors?

I've found the trick with the square plastic thingy's with the double faced tape is to stick them, then leave them for a day. Then load them up. Apparently the tape needs time to "set". I've had some in service for years. Unfortunatly you can't do that when you are on a job, and need to get it done and get on with it. I have the luxury of time, on most of my projects.
It also helps to make sure that the wires aren't trying to pull them off, ie bend the wires so that the tywrap just keeps them there, don't use it to pull them there.

It helps if you clean the surface before sticking them down, too. The little premoistened alcohol wipes from a drugstore work well.
