Ever notice how a wobbly Z-axis throws off your 3D prints? Layers shift, towers lean, and fine details turn fuzzy. These 150mm T8 lead screws with brass nuts fix that by delivering straight, repeatable motion you can count on.
Made with Tr8x2 Acme threading—a trapezoidal profile that's tough on wear but gentle on effort—these screws have a 2mm pitch and lead for controlled advancement. Each set includes two 5.9-inch (150mm) shafts and matching T8 brass nuts. Brass means low friction, self-lubricating qualities, and no galling like cheaper plastic or plastic alternatives.
Friction drops, so your stepper motors run cooler and quieter. Backlash vanishes, giving you prints with sharper corners and better tolerances—think 0.1mm accuracy without endless calibrations. In CNC routers, they handle side loads better than belts, keeping cuts true.
Drop these into Prusa, Ender, or Anycubic Z leadscrews with minimal tools—just a coupler and some thread locker. For SLA/DLP resin printers, they stabilize tall models that used to warp. CNC hobbyists love them for router lifts or mill spindles. Pro tip: Grease lightly with white lithium for years of whisper-quiet operation.
Steel shafts resist bending under load, and brass nuts won't strip like delrin. If you're modding a printer or building a custom CNC, these are the reliable choice without breaking the bank. Order a pair and feel the difference in your next project.
