## Questions & Answers

**Q: I have to ​refit an 8 mm ​b​olt into a cavity which we have no access to​.​ ​can this ​tool be used to insert a rivet nut​ ​into the hole. thanks, dr**
A: Typically this should be ok, you will require a sound surface to pull the rivnut onto, to make it work, but otherwise should work.

**Q: Where can I buy m5 replacement for this? (Uk)**
A: Hi Clare, Not too sure what exactly you are asking. The tool itself has mandrels for M5 Rivet Nuts and M5 Nuts are readily available through Amazon and others (Screwfix, Jewson,etc...).

**Q: Can I buy separately a m3 m4 m5 mandrels for this tool fitment**
A: Yes you can both Amazon & Ebay

**Q: Annoyingly mine came with zero instructions in the box.  Are they online anywhere?**
A: Don't think so, they are straight forward to use, but the smaller size ones don't need to much pressure or the mandrel could break.
