Size:T8x4 | Style:300mm+nut Packing list: 1 * T8x4 300mm lead screw 1 * T8x4 brass nut The lead of the thread is 4mm, which means that the nut will move 4mm if the nut turns one circle. The advantages of the lead screw are: Large load carrying capability Compact Large mechanical advantage Precise and accurate linear motion Smooth, quiet, and low maintenance, very suitable for 3D printer z axis. Minimal number of parts So this lead screw is very suitable for 3D printer Z axis, such as Ultimaker and Prusa i3. The screw type of this lead screw is ACME thread. ACME Threads are generally stronger than square threads due to their trapezoidal thread profile, which provides greater load-bearing capabilities.

Solved my bed drop issue on my Ender 5
Apparently the newer Ender 5 printers already come with a 2 start lead screw like this one. My original one was a 4 start so any time I paused the print or the print finished gravity would easily pull the bed down to the bottom. It cause all sorts of issues. This thing allowed my printer to hold solid after a print is completed. Now I can actually pause a print if I need to as well.

Works great
I used these to replace my stock Z Axis lead screw nuts on my Ender 5 plus. There were easy to install, smooth, quiet and they eliminated the backlash. I would recommend these.

Works great
Very nice! Worked great for dual z mod on my ender 5 pro. The lead nut is a little on the loose side but it wasn't even noticeable once it was in action on the printer.

Just what the doctor ordered
Fit perfectly, and stopped the build plate from creeping down when the stepper motor was turned off.Thanks!

Well packaged, arrived straight and true.
This item arrived in a cardboard tube, packaged inside a larger box. The screw was straight as an arrow and works well. Will buy more when I need them.
