ReliaBot 400mm T10 Tr10x8 10mm Lead Screw and Nut (2mm Pitch, 4 Starts, 8mm Lead) for 3D Printer and CNC Machine Z Axis

ReliaBot 400mm T10 Tr10x8 10mm Lead Screw and Nut (2mm Pitch, 4 Starts, 8mm Lead) for 3D Printer and CNC Machine Z Axis

Lead screw diameter 10mm, length 400mm, SUS304 stainless steel Brass nut, with 4 holes for fixing to the machine Thread: Acme thread Screw pitch: 2mm; Number of Thread/Start:4; Lead: 8mm (pitch*thread=lead) Suitable for higher load conditions than T8 lead screw Packing list:
1 * T10x8 400mm lead screw
1 * T10x8 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.
