## Overview

Permatex High Strength Threadlocker Red 50 ml is a premium adhesive solution designed for heavy-duty fasteners between 10mm and 25mm. Delivering 3,000 PSI of holding power, it permanently secures studs and press fits, resisting vibration and shock. This heat-resistant threadlocker seals threads against leaks, rust, and corrosion, ensuring long-lasting, rock-solid assemblies in automotive and industrial applications.

## Description

Permatex High Strength Threadlocker Red Formula is ideal for heavy-duty applications 10mm to 25mm and is especially well-suited for permanently locking studs and press fits. This high strength threadlocker adds 3,000 PSI holding power on slip and press fit assemblies and replaces set screws and snap rings. It also locks against vibration loosening. May require heat or special tools for removal. Applied as a liquid or gel, threadlockers are superior to conventional lock washers, nylon inserts, and other mechanical devices because they secure the entire fastener assembly against loosening from shock and vibration by filling the space between threaded metal parts, curing to form a tough, adhesive bond and seal. They also seal the threads against leakage, preventing rust and corrosion.

Review: It applied easily and seem to work well - I needed a threadlock for a couple of small set screws going into aluminum on a mower cylinder head. This went one easily and dried well. I did not try to remove the small set screw after it dried because it is something that will never need to be removed,, so I cannot say how tightly it locked the set screw in place. A little bit goes a long way, so the small tube will last me pretty much forever.
Review: GREAT PRODUCT AT GREAT PRICE - GREAT PRODUCT AND SO MUCH CHEAPER ON HERE THAN OUR LOCAL VENDORS

### ⭐⭐⭐⭐⭐ Permatex 27100 HIgh Strength Treadlocker is jus that - strong!!!
*by S***E on December 19, 2019*

This product states that it will require heating up the parts secured with this threadlocker to 500 degrees in order to separate the parts after the threadlocker cures, so you really need to be sure this is what you want it to do. 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!
