this is actually the 2mm pitch, other parts i bought said 2mm but actually they were 8mm pitch, due to that reason, i have to change the whole design. overall part qality is good. see the pic for comarision

Received the product faster than I thought. I placed the order on 9 september and I received the product on 26 september, Romania, near Bucharest. The lead screw and the nut works perfectly. I bought two of them. Each came with it's own bag and box. Great service.

I purchased the 200mm lead screw. The thread-form on the lead screw seems very good (surface finish and dimensioning). Appears to have been parted off to length on a lathe (rather than with a saw) leaving a clean cut. One end of the screw has a burr which prevents the nut from threading on, but the other end if fine. The burr looks easy to clean-up so i'm not concerned. The brass nut is a little loose-fitting to the lead-screw. Very little play axially but a noticeable amount radially; difficult to measure but i'd estimate about 0.25mm (0.01") which is likely intentional so the threads don't bind. Seems very good and i don't expect any issues using this for the z-axis in a CNC machine.
