Frequently asked questions
What is the difference between lead and pitch on this screw?
Pitch is the distance between thread grooves, here 2 mm. Lead is the linear travel per revolution, here 8 mm, because the screw has 4 starts (2 mm x 4 = 8 mm).
Which nut do I need with this lead screw?
The screw is sold without a nut. Use a nut that matches its 8 mm diameter, 8 mm lead and 4-start thread, and mount it in the Z-axis carriage of your printer or CNC machine.
