Great quality, precise movements, precise diameters.
reçu relativement rapidement une vis trapézoïdale, elle est bien droite (testé), semble solide, dimensions comme indiqué dans la description. livré avec son "écrou" dans un petit carton pour la protéger. Parfait.
Parfait pour axe Z repart. Bonne vis parfaitement droite . Cout imbattable. Merci

As beautiful as I expected. I am satisfied with this shopping.
Отличные валы
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.
Todo correcto.
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.
