TR8 8mm Anti-Backlash Lead Screw Nut - POM
Couldn't load pickup availability
TR8x8 POM anti-backlash nut for 8mm lead-screw Z axes. This three-piece spring-preloaded flange nut reduces axial play in TR8/T8 lead-screw assemblies while keeping the sliding surface POM/Delrin for low friction and wear resistance.
Why use the POM anti-backlash style?
- Spring preload: the split nut halves push against opposite thread faces to take up backlash as the screw and nut wear.
- POM body: self-lubricating plastic contact surface, quieter and lower-friction than a plain metal nut in many printer Z-axis builds.
- Drop-in flange format: common round flange body for printer lead-screw mounts.
Specifications
- Thread: TR8x8 / T8x8 trapezoidal lead screw
- Lead: 8mm per revolution
- Pitch: 2mm
- Starts: 4-start thread
- Material: POM / Delrin nut body with steel preload spring
- Mounting: M3 fastener holes, 18mm hole-center spacing
- Includes: one complete anti-backlash nut assembly
Fitment
Use this with 8mm TR8x8 lead screws on Z-motion assemblies, including Voron V0.1/V0-style and Voron Trident builds. It also pairs with the live Salad Fork Motion Kit and Voron Trident Motion Kit when you need a replacement or spare lead-screw nut.
Not for
- TR8x2, TR8x4, or single-start lead screws; match the lead and starts before ordering.
- Applications that require a metal/brass nut or a different mounting pattern.

Shipping:
US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.
International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.
I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or rerturned, I will not be responsible for rerturning your shipping cost.
If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.
Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
