It was exactly what I was hoping for, and it worked flawlessly by holding a barrel nut in the handle of my Colt 45 that had a screw that would not separate from the barrel nut. I put the threadlocker on the barrel nut, attached it to my Colt, and the next day - today, I was able to get the screw out of the barrel nut, but it took some force to get it to break free. The barrel nut did not budge at all, so kudos to Permatex! ## Frequently Bought Together - Permatex 27140 High Strength Threadlocker Red, 36 ml - Permatex 24240 Threadlocker Blue Medium Strength,Thread Lock & Screw Glue for Bolts Nuts & Fasteners to Prevent Loosening & Corrosion, Removable with Hand Tools 36 ml - Permatex 25210 High Strength Removable Threadlocker Orange Liquid, 10 ml --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://virgin.desertcart.com/products/5576564-permatex-red-threadlocker](https://virgin.desertcart.com/products/5576564-permatex-red-threadlocker) --- *Product available on Desertcart British Virgin Islands* *Store origin: VG* *Last updated: 2026-10-07*
