Removing LOCTITE® high-strength threadlockers can be difficult, and it’s a common vehicle maintenance question. While the performance of our high-strength threadlockers is formidable, and meant to be a permanent assembly method, don’t believe the myths: high-strength threadlocker can be disassembled with the right technique.

Removing high-strength threadlocker

The process of knowing how to remove high-strength threadlocker is a little different than for other threadlockers. The key is to apply localized heat greater than 250°C (550° F). Then, once the threaded assembly is hot, the bolt can be unthreaded. Without applying heat to the assembly, some bolts threaded into tapped holes risk breaking.

Commonly asked questions

Is it possible to remove high-strength LOCTITE® threadlockers without heat?

When the threads are locked, even the most aggressive solvents are unable to weaken a high-strength threadlocker due to the limited surface area for the solvent to attack. Only by using heat can you penetrate and remove high-strength LOCTITE threadlocker in an assembled joint.

How to clean and remove high-strength LOCTITE® threadlocker from threads?

When a threadlocked bolt is disassembled and needs to be reused, the cured high strength threadlocker will need to be removed from the threads. The cured LOCTITE product can be removed with a combination of soaking in a solvent and mechanical abrasion such as a wire brush. For female threads, a tap can be used to clear the threads instead of a wire brush.

What will dissolve high-strength LOCTITE® ?

LOCTITE SF 7200 can be used to soften cured high-strength LOCTITE. Mechanical abrasion will also be needed to assist with the removal.
