Review: Great kit - I used this kit to fix a motorcycle bag I own. The plastic in the back of the bag was too thin and I needed to replace it with something thicker. They originally used rivets and I used these instead. I also used washers and it worked out great. so far these have turned out very well.
Review: Great - I love this collection/sellection.Super !!

## Questions & Answers

**Q: are these 5mm shafts accurate enough to be used with 5mm ID bearings?**
A: Hmm.  these are binding screws, not what I would call "shafts".  If you are thinking of them to use as a rotary shaft in bearings...I would expect them to fail very quickly

**Q: Are these screws magnetic?**
A: These are screws.

**Q: Do you have longer M4 screws?**
A: The size of the screw top is M4*5(diameter of the screw is 4mm,thread length:5mm). currently,we do not have longer thread length. The 5mm screw tops can be used with all of the screw post in this box.
