Lead screw diameter 8mm, length 150mm, SUS304 stainless steel Brass nut, with 4 holes for fixing to the machine Thread: Acme thread Screw pitch: 2mm; Lead: 8mm If you want higher accuracy, it is recommended to use the anti backlash brass nut Packing list:
1 * T8x8 150mm lead screw
1 * T8x8 brass nut
The lead of the thread is 8mm, which means that the nut will move 8mm 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.
