What's included 1 x T8 lead screw (8 mm diameter) 1 x matching nut Key benefits — why you need this Converts rotary motion into precise linear motion for accurate positioning and repeatable travel. Smooth operation and welldefined threads reduce backlash and wear, improving performance in motion systems. temperature resistance maintains function under heat exposure, useful in machines that generate heat or operate in warm environments. Core specifications (exact) Type: T8 lead screw with matching nut Diameter: 8 mm Thread direction: righthand Thread pitch: 2 mm Lead: 4 mm (one full nut rotation advances the screw 4 mm) Thread quality: clear lines and smooth cut for dependable engagement Performance and compatibility Designed for standard T8 mounting and assemblies; suitable wherever a T8 8 mm screw is required. Precise pitch and lead ensure consistent travel per revolution (4 mm per nut turn), useful for synchronizing belts, motors, or handdriven adjustments. Smoothly machined threads minimize friction for quieter, longerlasting operation. Practical use scenarios 3D printers: or upgrade the Zaxis lead screw and nut to restore accurate layer height control and reduce wobble. CNC and milling jigs: use for small linear stages or custom fixtures that require predictable linear travel and heat resistance. DIY automation and robotics: implement in linear actuators, camera sliders, or pickandplace mechanisms where reliable, repeatable motion is required. Why this part stands out Exact T8 dimensions (8 mm diameter, 2 mm pitch, 4 mm lead) give predictable motion characteristics for integration with stepper motors and manual adjustments. Nut and screw supplied together for immediate assembly and testing. Built to provide smooth engagement and maintain performance under elevated temperatures. Ordering tip Confirm your system requires a righthand T8 screw with 8 mm diameter, 2 mm pitch and 4 mm lead before to ensure compatibility.
