Go to eBay and search for "SFU1605" That is a 16mm diameter by 5mm pitch screw. These come with nuts that had best NEVER be removed
I could not find drawing of the part anyplace so I made one myself. If you want I have .STEP file These screws are a standard part and come of different grades. The ones on eBay are the lowest grade. C0 is the best and has about 3 micrometer error per meter and are used for things like making integrated circuits. These low-spec parts are maybe 10X worse but I don't know how to measure to micrometer level over a 1000 mm distance. My guess is that all the screws are made on the same machine, then they inspect them for grade so a low spec part might be as good as a high spec part? I think there are other sizes available. I've seen 12mm diameter and some larger too.
