Review: The Unsung Hero of My Toolbox - This little green tube is the ultimate bolt babysitter. I had screws on my lawnmower that thought they were auditioning for Cirque du Soleil—constantly twisting, flipping, and popping out. One drop of this threadlocker, and suddenly they’re calm, stable, and finally committed to staying put. What I love most is how easy it is to apply—no crazy odor, no giant cleanup, just a drop that does the job. It seeps in like magic, and the next thing you know, your hardware is locked in like Fort Knox. If you’ve got machines, bikes, or gear that rattles apart, this is basically the duct tape of bolt security—only classier.

## Questions & Answers

**Q: Is this product electrically conductive?**
A: NO.  They are plastic and will insulate just the opposite of what they want.  No electrically conductive anaerobic threadlockers

**Q: How difficult will some torx-drive #6 and #8 adjustment screws be to break loose and readjust in the future if I use this stuff?**
A: I wouldn't use this, it sets up very hard. Use the red or blue, be much easier to adjust a at later date.

**Q: Are these ideal for wheel spacers ?**
A: You may want to use a retaining compound like Loctite 638 for this type of application, just make sure to have a clean surface and tight gap between the parts, thank you.

**Q: I need something to keep the screws tight in my eyeglasses.  Is this product overkill for that application?**
A: yes, it is too strong. Use Loctite 222 on screw, then assemble. Or you can use Loctite 220 after assembly, it is the low strength penetrating.
