15-in-1 400mm Full Thread Rod T8 Parent Screw with Brass Nut Kit Key benefits Precise T8 thread for accurate linear motion: clear, fully formed threads ensure uniform force along the shaft and smooth sliding during operation. Ready-to-install kit for stable, continuous performance: every threaded rod in the kit comes with a brass nut to secure fittings and maintain consistent motion under load. Versatile and reliable for machine components: designed to simplify assembly and reduce wobble and backlash in driven linear systems. What you get 15-in-1 kit containing full-thread T8 parent screws, each 400mm long, paired with brass nuts for tightening and secure mounting. Primary features Thread type: T8 thread, full-length threading for maximum engagement across the entire 400mm shaft. Size: 400mm length—suitable for many common machine configurations. Material: steel threaded rods with brass nuts included for tightening and mechanical connection. Performance: clear, full threads provide uniform force transfer and smooth sliding motion for repeatable movement. How it solves problems Eliminates inconsistent travel and binding by using full-length, high-definition T8 threads for even load distribution. Reduces the need for constant adjustments because brass nuts provide stable tightening and maintain position under continuous use. Simplifies upgrades and repairs by supplying a matched set of rods and nuts that are ready to install. Compatible applications and use scenarios 3D printers: Replace or upgrade Z-axis screws to restore precise layer height control and reduce vertical backlash. CNC machines: Use as lead screws in small gantries or linear stages for repeatable positioning and smoother toolpaths. Automated equipment and molding machines: Install in indexing assemblies or actuator-driven parts to maintain steady, continuous operation. Who this is for Hobbyists and professionals repairing or upgrading 3D printers and CNC routers.
