## Questions & Answers

**Q: The thread inserts are too small to use in a crank**
A: What type of crank?  I am trying not to say, buy the right thread then.

**Q: Does the kit come with a case and the tools**
A: The ad shouldn't have put kit, as you only get the thread inserts in a bag! No case or tool. If you have some steel rod, bend a 90° angle on one end & you put a slice in the other end with a hacksaw or fine cutting disc, if you have an angle grinder & you could make a tool! Thats what I did!
