Review: Awesome product - Worked great to keep the screws tightened in our bathtub faucet handles. Easy to apply! Every time we turned the water on the screws in the handles would loosen and the handles would rattle. I finally got this product, put it on the screws, tightened and let it sit over night and the screws are now solid tight and problem is solved. It has been months now and still holding strong! Thanks!

## Questions & Answers

**Q: Is there a solvent or dremel attachement that will remove this stuff from bolt threads?**
A: You don't need solvent or dremel.  It will keep any screw or bolt from loosening, but you can get the bolt/screw out with a screwdriver and just brush off the Loctite.   Very good stuff.

**Q: Do I apply this to my doorknob set screw before screwing it in or after? (ie, a drop on top?)**
A: Before. You apply this to the screw threads before screwing in. Make sure you only apply a very little bit. More is not better.

**Q: how do I open the sealed tube? do I just poke a hole at the top?**
A: I think it's best to use a thumbtack, safety pin, etc. to poke a hole into the flat tip. This will give you "droplet-sized control" in application.

**Q: can this be used in glasses?  The screws that hold the lenses in place?**
A: No, it is designed for larger screws.  Use Loctite 222 for small screws.
