Steel Lead Screws
ZTW's CNC machine kits come with leadscrews with antibacklash nut to eliminate the backlash. There are two types of leadscrew we carry. One is our regular leadscrew that has 1.25 mm lead. Another one is our F8 leadscrew, which has a 8 mm lead. Below is the total length(mm) of the leadscrews on different axis.

Our Regular leadscrew is using brass anti backlash, and our F8 is using Ultra-high-molecular-weight polyethylene and brass for anti-backlash assembly.
