Very good

I decided to switch my stock lead screw from an 8mm lead to this 2mm lead, along with replacing the sloppy brass nut for a matching POM version WOW My current single z is a standard 1.8 degree stepper which completes 200 turns per 1 full mechanical revolution, with this lead screw running full steps it takes 100 turns/mm which equates to 0.01mm per full step or at 16x microstepping 0.000625mm per microstep. After changing these two components I decided to jump down to play with my 0.2mm nozzle and print some minis, the layer accuracy does seem drastically improved in general but even better for small things, 2nd z parts now ordered

received item as described thank you

Just what I ordered for a dual Z setup. Nice and straight too.

got 2, both came packaged well, and worked like a charm with the backlush nut. Had to print an adapter for 3drag for specific nut size

Upgrading my 3D printer to dual z this lead nut with the lead screw will do the trick. Probably a better part than the original.
