Page 6 of the DVX100A user manual (found here online: https://service.us.panasonic.com/OPERMANPDF/AGDVX100A.PDF ) states that there are four screws total that come for the mic holder/adapter. Two 12mm for the holder to attach to the adapter. And two 6mm screws to connect the whole thing to the camera itself.

In your post you say you’ve lost the two that connect the whole thing to the camera. That would be the 6mm in length (XSB4+6FZ) models.

Head over to here:

And in any of the part number windows paste in this:
XSB4+6FZ

There you go. $1 for each screw. They call it a BINDING HEAD SCREW.

To be honest, I live in Philadelphia. Neither the Lowes or Home Depot had the screws. But a wonderful independent hardware store called Rittenhouse Hardware on 20th and Pine DID have the screws. For about 30 cents each. They’re tight as a drum, solid as a rock. The exact fit.

I’d bring your camera and mic holder to your local NON-CHAIN harware store and see if they got em. My screws were traditional silver colored, not the black that the Panasonic screws come in. But honestly, does that matter much?
