Wyze thermostat screw size

what are the size of the 2 screws for the wyze thermostat? Are they hex head? I lost them and the manual does not explain.

thanks

The installation video shows + style screw. Doesn’t state the size. I would take the mounting plate to a hardware store and find a screw that fits in the hole and is long enough, just measure the length of the provided wall anchors.

thanks for the help
