2PCS T8 Anti-Backlash Nut Kit – Spring Loaded POM for 3D Printers
Upgrade your 3D printer or DIY CNC machine with this precision-engineered T8 Anti-Backlash Nut Kit. Designed to eliminate unwanted play and wobble in your lead screw system, this spring-loaded POM nut delivers smoother, more accurate movements — giving you cleaner prints and better overall machine performance.
Made in Mainland China.
Key Features
- Eliminates Backlash: Spring-loaded dual-nut design cancels out thread gap, ensuring precise and repeatable positioning with every move.
- High-Quality POM Material: Polyoxymethylene (POM) construction offers excellent tensile strength, a low friction coefficient, and long-lasting stable performance.
- Easy to Install: Standard sizing fits the T8 lead screw out of the box — no modification needed.
- Quiet Operation: Smooth POM-on-steel contact minimizes noise during use, ideal for home workshop environments.
- Wide Compatibility: Works with Creality CR-10, CR-10S, Ender-3, Ender-3S, Ender-3 Pro, and most other T8-compatible 3D printers. Mounting holes are M3 spaced 18mm apart.
- Versatile Use: Suitable for 3D printers, DIY engraving machines, and any precision linear motion application requiring backlash reduction.

Frequently Asked Questions
Q: What 3D printers are these T8 anti-backlash nuts compatible with?
A: These T8 POM anti-backlash nuts are compatible with Creality CR-10, CR-10S, Ender-3, Ender-3S, and Ender-3 Pro, as well as most other 3D printers and DIY CNC machines that use a standard T8 (Tr8x2 or Tr8x8) lead screw. The mounting holes are M3 with 18mm center-to-center spacing.
Q: What is the difference between Tr8x2 and Tr8x8 configurations?
A: Tr8x2 refers to a 2mm pitch single-start lead screw, while Tr8x8 is a 4-start screw with an 8mm lead per revolution. Both use the same 8mm diameter nut body, so this kit covers both configurations — simply select the appropriate pitch for your lead screw setup.
Q: How does the spring-loaded design reduce backlash?
A: The spring-loaded mechanism keeps constant tension between the two nut halves, compensating for any thread play in the lead screw. This eliminates the small gap (backlash) that would otherwise cause imprecision or "ghosting" in your prints, resulting in sharper, more accurate output.
Q: Is installation difficult?
A: Not at all. The nut kit is designed to standard T8 dimensions and simply screws onto your existing T8 lead screw. Secure it with the included M3 hardware into the 18mm-spaced mounting holes on your printer's carriage and you're good to go — no special tools required.
