I have occasionally used snap in connectors for MC and Romex. Not my favorite but good for some uses. I have a few projects where they would be handy now for EMT. I've seen a few EMT snap ins on the web but not in stores. Has anyone tried them?

Are you referring to the ones that look and work like the sharkbite for plumbing? If so haven't tried them but know questions have been raised about the ability to use them if the EMT is used as the EGC as allowed in code, and their ability to make an effective bond.
 
Snap in like the old Sierra/Tomic fittings? Or set screw fittings that snap in w/ no lock nut required? The Tomic connectors did require a locknut, but once installed on the EMT had to be cut off.
 
I was running MC the other day and I needed a 90 connector. The only one I had on the truck was a snap-in. I held my nose and installed it. I don't like anything I can't undo easily. I have seen guys say they won't even glue PVC together.
 
Garvin, Arlington & Bridgeport have them on Google. Garvin one looks good. I'd probably not find them around here though.
 
I've used them a couple of times.
The last time was about 2 months ago where I had to make my own knockouts in some linear LED up/down lights. There was not enough flat space inside the end cap to get a lock ring set, so snap-ins were my only real choice.

They worked ok, but definitely not my first choice

Thanks for this.

I sometimes do projects where I run EMT to air compressors and other machines for data lines. I pipe ahead of the project and have wire pulled to nearest box to be ready. A snap in connector would be good here so that I don't have to crawl around inside the machine at shutdown to get a locknut in a difficult location. I could snap through, feed wire in and have it waiting when terminations begin. I can safely open a panel on some machines to snake wire.

Will these make a proper tight connection to allow the EMT to be used in accordance with 358.60 as a grounding conductor?

Yup. For me it was all about the lock ring. Seems your scenario would be a good fit
 
I thought about the grounding too but it wouldn’t concern me much with data cables. Machines are already well grounded with GEC’s & secure electrical conduits. Plus, my data conduits are secured well to building steel.
