T8 Anti-Backlash Spring Nut — precise, durable nut assembly for T8 lead screws Why you need it Eliminates backlash and axial play in T8 lead screw systems for more accurate linear positioning. Produces smoother, quieter motion and cleaner cuts or prints by maintaining constant contact with the screw threads. Protects your equipment investment by reducing wear on the lead screw and driven components. Key benefits Improved precision: anti-backlash design keeps motion repeatable and tight, ideal for CNC, 3D printing, and precision stages. Longer component life: brass nut parts and the spring maintain engagement while resisting galling and wear. Reliable performance: corrosion and rust protection plus high-temperature resistance ensure stable operation in demanding environments. Specifications Overall size: 45 x 22 x 13.5 mm Lead options: 1 mm, 2 mm, 4 mm, 8 mm Pitch options: 1 mm, 2 mm Material: nut parts made of brass; includes spring for anti-backlash function What’s included 1 set T8 anti-backlash spring nut (each set contains 2 brass parts and 1 spring) Compatibility and fit Designed for T8 lead screw assemblies with the listed lead and pitch combinations. Verify your lead screw’s lead and pitch before installation. Compact 45 x 22 x 13.5 mm profile fits common mounts and carriage designs for retrofitting or new builds. Performance and durability Smooth operation reduces vibrations and mechanical noise. Corrosion-resistant and heat-tolerant materials support consistent performance in higher-temperature or humid environments. Clear thread engagement yields more precise motion transfer and cleaner results in machining or printing. Typical use scenarios 3D printers: reduce backlash on Z-axes and improve layer registration for higher-quality prints. CNC routers and milling machines: tighten toolpath accuracy for better surface finish and dimensional control. Robotics and linear actuators: increase repeatability for positioning systems, test rigs, and automated stages. Installation notes Replace or retrofit into T8 lead screw assemblies matching the specified lead and pitch. Ensure proper alignment and preload when installing the spring nut to achieve optimal anti-backlash performance. This T8 anti-backlash spring nut set provides a simple, effective upgrade to tighten mechanical play, improve accuracy, and extend the service life of your lead screw-driven systems.
