Official answer from the nest chat is "diameter 3.5mm and 13mm length
including head". I cut down some M3.5 from UK electrical sockets and
used a washer but you can find similar on ebay.co.uk item 234104165322
or (from Falcon) 201634955749. Hopefully...
Looked all over the shed and then the Internet for these screws orthis
information. Did you get an outcome? I have the stand but no screws.
Tried M4 machine screws but they are not right.
