Help! Lost Mrount camera bracket screws

In the confusion of cleaning up after Christmas, the 4 tiny screws that hold the halves of an Mrount bracket together for mounting a Wyze Cam were evidently tossed by mistake. I can’t find anything nearly small enough at the local hardware stores.

Google searches for “Mrount” only yield Amazon results.

Does anyone know a source for the screws, or even what size they are? If so please inform me here or in PM at jpv993(at)earthlink.net

Thanks in advance
