Review: Easy to use, works great. - Used this to fix a screw on my elliptical machine that kept coming loose when I used it. Very easy to use, just squirted the Threadlocker onto the bolt, attached it to the screw, and let it dry. It never comes loose anymore.

## Questions & Answers

**Q: What is the exasperation date?**
A: Exasperation date is when early on in a relationship, you realize the male is never going to put the toilet seat back down. Then you accept him for the person you love, and not the genetic XY Toilet Seat Disorder he has. So you marry, and then, he also all of a sudden, forgets to flush every. Single. Time.
That my friend is an exasperation date. 
On another not, speaking of this product, and it’s expiration date, you’ll find it crimped on the bottom of tube, I personally haven’t received an expired one yet. My advice? Contact the seller directly, you should be able to click on the seller and pull up at least an email. And ask how far out are the current expiration dates on the products they are shipping out now. If they beat around the bush, look elsewhere because they absolutely should have at the very least an estimated time period. Hope this helps my friend. Because my exasperation has no answer minus purchasing a shock collar for humans. FDA approved ofc, I’m not about torture or etc

**Q: What is the best temperature what is to hot for this product**
A: temp. ranges are -65 to 300 degrees F.

**Q: Can it be used for gun sights?**
A: I would NOT use the Permatex MEDIUM STRENGTH Loctite on ANY fastener that is less than 1/4" in Diameter. Doing so can result in STRIPPING out the thread when you attempt to remove the fastener. It is very strong! That would include small set screws as used on weapon scope mounts. For fasteners that are less than 1/4" use Permatex LOW STRENGTH type 222 PINK COLOR. you can find it here on Amazon at a ridiculously low price. You will be able to remove the fastener fairly easily without seizing and stripping the threads. Clean the fastener threads with acetone to remove all oil/grease from the threads and air dry. Apply a small amount to the threads and wipe off the excess with your fingers. The Loctite cures in the absence of air. Make sure you thoroughly wash your hands after using any Loctite product. I hope this helps!

**Q: would this work well with a balisong (butterfly knife) screws?**
A: It will keep what ever it touches firmly in place. With your application, if the screw has any interaction with the moving parts or the tension of the knife (how easily the knife blade moves) I would urge caution. This blue stuff is not permanent but it will take considerable effort to remove the screw.
