High-precision T8 lead screw assembly engineered for reliable linear motion in 3D printers, CNC machines, robotics, and automation systems. Key features Available lengths: 100 mm, 200 mm, 300 mm, 400 mm, 500 mm, 600 mm, 750 mm, 800 mm Material: Stainless steel lead screw with brass nut for low friction and long service life Package includes: 1 x T8 lead screw + 1 x nut Thread options: Pitch options: 1 mm, 2 mm Lead options: 1 mm, 2 mm, 4 mm, 8 mm Why you need this lead screw Accurate, repeatable linear movement for positioning and Z-axis control. Durable stainless steel and brass construction minimizes wear and reduces play over time. Single-screw package with matching nut simplifies replacement or upgrade of existing motion systems. Performance and compatibility Multiple lengths let you match the screw to your machine frame without cutting or modifying. Choice of pitch and lead lets you balance speed vs. resolution: higher lead gives more linear travel per rotation for faster motion; lower lead gives finer resolution and greater mechanical advantage. Compatible with standard T8 lead screw coupling systems and common stepper motor-driven assemblies (verify fit with your hardware). Typical applications 3D printer Z-axis: replace worn screws or upgrade to reduce wobble and backlash. CNC and router machines: use for small linear slides and vertical motion control. Robotics and automation: reliable linear actuation for lifting, positioning, and test rigs. Quick selection tips Select length that fits your rail and clearance requirements. Choose pitch/lead based on desired trade-off between travel speed and positional resolution. Included brass nut installs directly on the lead screw for immediate use. What’s in the box 1 x T8 lead screw (selected length) 1 x matching nut (brass) If you require a specific combination of length and lead/pitch, choose the matching SKU to ensure compatibility with your machine.
