## Questions & Answers

**Q: What is the pitch?**
A: 2mm

**Q: Will this work as a replacement T8 screw for the Ender 3?**
A: sorry   yes this is a 4 start screw  good for dual z application on the ender 3

**Q: Is the coupler 8mm to 5mm? It looks like it in the picture, but does not say anywhere.**
A: yes mine was, they should mention that  in the description but be aware, they could change couplers from when I got mine. I'd say get this kit but be ready to get a coupler just in case.
