How to mount LS23001 GPS?

Any got any ideas on how to measure the LS23001 ( GPS receiver?

The mounting holes are 2mm diameter - having trouble finding useful/cheap screw/nuts/standoffs at that size.


How about some M1.5, M1.6 or M1.8 screws with matching nuts? Can be bought in any place selling screws, those are fairly standard. They might not have all of them but usually one of those sizes is in stock.


Or ebay. I found ebay was good for nuts and bolts that size, my local B&Q didn’t stock them.
