Leadscrew - TR8x8 - 300mm

Out Of Stock Leadscrew - TR8x8 - 300mm

These high-quality TR8x8 leadscrews are the same ones we use on our Aus3D Prusa Mendel i3 3D Printer kits. We've put them to the test, and are satisfied that these leadscrews are perfect for 3D printer use. They make a great upgrade from a threaded-rod setup, and deliver motion that is quick, smooth and consistent.

These are TR8x8 leadscrews - they're 8mm diameter, and the brass carriage nut will travel 8mm for every rotation of the leadscrew. Check below for a table of Z steps / mm values!


  • Length: 300mm
  • Thread: TR8x8
  • Starts: 4
  • Pitch: 2mm
  • Lead: 8mm
  • Material:
    • Stainless Steel (Leadscrew)
    • Brass (Carriage Nut)

Printer Z Steps:

This table should help you find the right steps / mm setting for your printer using these leadscrews - if you need a hand with a different setup, let us know!
