## 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.

*by M***L on March 28, 2026*

Since i started applying it to my bike bolts, they stay tight longer. it's nice that it’s removable if needed without much hassle. the small 6 ml bottle lasts quite a while, and it really gives me peace of mind knowing my fasteners won't come loose unexpectedly. simple to use and works well for keeping things secure on the go.
