## Questions & Answers

**Q: How hard is to pull the two halves apart?**
A: You can separate the halves with your hands. They are friction fit together but not under any significant pressure. I use them for my two Z axis screws on my 3D printer (motors at bottom) which are always under pressure from the X carriage and they have never separated after 1000+/- prints.

**Q: these actually grip the lead screw right? because the stock spring style, my lead screw crawls up it inside, causing binding, due to poor QC thx**
A: I had problem with mine slipping, No amount of tightening that screw would cause it to hold fast. Resolved with a few drops of CA glue.

A: Yes,it can be used for cr10s pro v2

**Q: Which size to get for CR10V3?**
