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. ## Frequently Bought Together - Permatex 24300 Surface Insensitive Threadlocker Blue, Thread Lock & Screw Glue for Bolts Nuts & Fasteners to Prevent Loosening & Corrosion, Removable with Hand Tools 10 ml - Permatex 27200 Hiigh Temperature Threadlocker Red, 10 ml - Permatex 25210 High Strength Removable Threadlocker Orange Liquid, 10 ml --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/4036826-permatex-24300-surface-insensitive-threadlocker-blue-10-ml](https://www.desertcart.it/products/4036826-permatex-24300-surface-insensitive-threadlocker-blue-10-ml) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-07-24*
