I recently ordered an ACOG mount and FF Rail and both packages had blue LOCKTITE to coat the threads with. My question is this; Is locktite an anti-seize compound, concrete glue, grease, etc. What is its main purpose? Can screws that have been coated with locktite ever be removed? Thanks guys. |

It's like a glue. It prevents screws from unscrewing under normal circumstances. It takes just a little more pressure to unscrew it. There are varying strengths of loctite. Blue breaks free rather easily, while red is never intended to come loose. I've heard green loctite is designed specifically for firearm applications, but I've never seen any. It holds almost as strong as red, but breaks free almost as easily as blue. |
| Loctite is an anaerobic adhesive... that is, a glue that cures only in the absence of oxygen. As mentioned, there are various strengths, but for your applications you only need blue; blue Loctite will stop screws shaking loose, but can be removed with ordinary tools. Red is permanent (need lots of heat to remove). Green is penetrating, i.e. can be squirted on the outside of a join, and it will wick its way inside by capillary action... I have used it to hold pistol sights secure in their dovetail after tapping into position. |
