TR8x4 lead screw made from stainless steel with an 8mm diameter, 2mm pitch, 4mm lead, and 2-start thread design for compatible linear motion assemblies, 3D printers, CNC-style projects, and custom mechanical builds.
Price range: $12.49 through $17.49
The TR8x4 lead screw is an 8mm diameter stainless steel Acme threaded rod designed for compatible linear motion assemblies, 3D printer builds, CNC-style motion systems, Z-axis setups, and other mechanical projects that use TR8x4 lead screw hardware.
This lead screw features a stainless steel construction, 8mm diameter, 2mm pitch, and 4mm lead. The 2-start thread design means the nut travels 4mm for each full rotation of the screw, making it suitable for compatible motion systems where controlled linear travel is required.
This product is available in three separate length options: 380mm, 480mm, and 580mm. Each size is sold separately, allowing you to choose the length that best matches your printer, machine, or custom build requirements.
Compatible anti-backlash nuts and standard lead screw nuts are also available from dnb3D. These parts are commonly used with TR8x4 lead screws to build or repair Z-axis assemblies, lift mechanisms, positioning systems, and other screw-driven motion projects.
This stainless steel TR8x4 Acme lead screw is useful for a range of compatible linear motion applications. While commonly used in 3D printers, it should also be positioned as a general-purpose motion component for makers, builders, repair work, and custom mechanical assemblies.
Browse more lead screws, 3D printer accessories, and 3D printer parts for compatible motion hardware, repair parts, and custom build supplies.
Pair this lead screw with a compatible anti-backlash nut or lead screw nut for supported TR8x4 linear motion assemblies.
For a clear explanation of how pitch, lead, and thread starts relate to lead screw movement, see this guide from Thomson Linear.
Before ordering, verify the required lead screw length, diameter, pitch, lead, nut compatibility, coupler size, bearing support, and mounting layout for your project.
Each TR8x4 lead screw is sold separately. Select the required length before adding the product to your cart.
