I change my desk like others change their wardrobe. Needless to say, I have a smorgasbord of Vivo monitor mounts, but I only had one clip. They should send screws at the end or just tell you what size to buy. Instead, I searched the manual for the full hand, found the list of included hardware, and went from there. The clip itself is great so I went with Vivo details. Screw details: Manual says 3 countersunk screws M5x15. M5 = 5mm. You will need a 5mm x 12mm or 16mm pan head machine screw; I couldn't find 14mm in any hardware store.
