## Questions & Answers

**Q: So "free spinning" means once screwed on, the knob continues to spin?**
A: In this sense "free spinning" means it does not have a nylon locknut type ring. Their sister product, B00GORY4E6, has the nylon ring to provide some grip to resist loosening due to vibration, etc.

**Q: is this good for 8m screws?**
A: No, these are for 1/4x20 bolts. An 8mm screw is too big and will have a different thread.

**Q: what is the quantity,1 place says 1 and another says pack of 10?**
A: My package was 10 knobs. The add says 10 knobs in 1 package so you get 10.

**Q: Do these have the nylon lock washer inside? the picture is the same cgi as the other offering.**
A: No nylon lock washer. Just metal thread insert.
