Incorrectly assumed this was a cast part. It's not. It's a plastic housing. Still does the job.

I've got a couple of generic articulated mic arms that came as kits with SM7B mics many years ago. they have a nub that sticks down and goes into a hole. Is this item suitable for desktop mounting for those?
No. It seems like the nub that you are referencing on the SM7B would connect to a mic stand or broadcast arm. The Shure A400SM is made for compatibility with gooseneck models like the Shure MX418 for example.

Would this mount work for an earthworks fm500 gooseneck mic?
Yes, the Shure A400SM Recessed Shockmount for Gooseneck Mics should accommodate the size of the 3-Pin XLR male base connection on the Earthworks FM500 Flexible Podium Microphone. The A400SM does not provide any audio connections, however. A cable would need to connect to the FM500 base on the underside of the mount.
