## Questions & Answers

**Q: Is that straightness number correct (0.8mm)? That's not very straight. Should be more like 0.06mm.**
A: Thans for your question. We check it again, it is indeed our mistake. Its straightness number should be straightness be below 5μm/100mm. We have upated this data on our page.

**Q: Is it possible to get these with both ends tapped with an M6 thread?**
A: I haven't seen any that were drilled and threaded that weren't a custom length OEM part.  I had no issues drilling and tapping them using just a cordless drill, the outside layer is hardened so if you grind that off first it's much easier.

**Q: When will the 700mm X 12mm be back in stock?**
A: Dear Customer

Thanks for your trust. About 10 days 700mm X 12mm will be back in stock.

**Q: Can I thread the ends of the rod or they are too hardened to allow it ?**
A: You can thread them all day long with a lathe if you like, but first you have to remove the chrome (chemically or with abrasives) and anneal the section of the rod that you need to thread. Otherwise, you'll need to grind the threads with silicon carbide or diamond.
