Review: Works as it should. Excellent product - What else can be said about blue loctite. Use sparingly. A little can go a long way. Easy to use. Great value. Holds screws in place as it should
Review: Useful for bike repairs and loose bolts - X when working on my bike, the Loctite Blue 242 helps secure bolts nicely. It stays in place but still comes off when I need to remove parts later. The medium strength is just right for most jobs around the house and in the garage. The 6 ml tube is small but lasts through multiple projects. It does what I need without any hassle or mess.

## 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.

### ⭐⭐⭐⭐⭐ Works as it should. Excellent product

### ⭐⭐⭐⭐⭐ Useful for bike repairs and loose bolts
*by R***Z on April 11, 2026*

X when working on my bike, the Loctite Blue 242 helps secure bolts nicely. It stays in place but still comes off when I need to remove parts later. The medium strength is just right for most jobs around the house and in the garage. The 6 ml tube is small but lasts through multiple projects. It does what I need without any hassle or mess.

### ⭐⭐⭐⭐⭐ Best stuff to keep your threaded parts together! Can be removed with some effort, not by accident!
*by E***S on February 27, 2026*

I have used this for more than 40 years. Always works. Easy to apply (More is not better). A slim stripe along the threads will do the best and will permit you to break the seal, with some effort. Whatever threads you "locK" will not unthread due to vibration or stress but can be unlocked, if needed. Especially effective on loose or worn threads. A little bit goes a long way. I usually apply it to the threads sparingly for best effect. If you want the threads to permanently NEVER come loose, use the Red. Have always had a tube of this around for the last 40 years. No need to overtorque (tighten) and risk stripping threads or breaking a bolt.
