Loosen the threadlocker - the heat makes it

Especially on devices that move or only slightly vibrate, screws are like high-strength secured by a professional with a screw lock. If you later try to remove the secured screw yourself, there is usually a lot of frustration and a damaged screw. Here we show how a screw lock is released.

Thread locking medium strength or high strength

Depending on the type of use, screws are provided with a screw lock. This, for example, serves to protect things against theft. These may be solar panels or other expensive additions to corporate or residential buildings. The second variant of why screws are secured medium-tight are motors or moving parts. Here the screws are secured, because they could easily shake off by the movement.

Avoid raw violence

Under no circumstances should a secured screw be loosened with brute force. This would only damage the screw at least, more likely the engine or the construction will be damaged.

Release screw lock - use correct tool

For special screws, for example, the solar panels, there is usually a special tool with which the screw connection can be solved easily again. Again, no other self-made alternatives should be used.

Remove paste for thread locking

The screw must be heated as well as the connecting surface strongly. You should only do this yourself if there are no rubber parts in this area. For most screw connections, this can be done with a Bunsen burner. If the parts are more sensitive, a hot air blower may also be a good service.

Use the correct paste

So you do not have too much trouble with a screw lock later, you should always use the right paste. The more often the screw has to be loosened again, the lower the strength of the paste should be. For example, Loctite has these three varieties:

  • Low profile threadlocker
  • Thread locking medium strength
  • Threadlocker high strength

Tips & Tricks

Usually, after loosening a Loctite connection, a dry residue sticks to the screw connections. These residues are difficult to scrape off completely. If you do not want to bother forever scraping off those dry hard rests with the wire brush, you can work with heat here as well. Depending on the component, the paste residue can be burned with a Bunsen burner.
