Thread locking medium strength or high strength
Depending on the type of use, screws are provided with a thread 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.
Loosen the screw lock - use the correct tool
For special screws, for example for the solar panels, there is usually a special tool with which the screw connection can be loosened again without difficulty. Again, no other self-made alternatives should be used. Entfernen Remove the screw securing paste.
The screw must be heated as well as the connecting surface. 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
To avoid later having too much difficulty with a threadlocker you should always use the correct paste. The more often the screw has to be loosened again, the lower the strength of the paste should be. There are, for example, three types of Loctite:
- high-strength threadlocker
- tips & tricksMore often a dry residue sticks to the screw connections after loctite loosening. 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.
