justeringsskrue

A "justeringsskrue," which translates to "adjusting screw" in English, is a type of screw designed for precise fine-tuning of mechanical components or settings. Unlike standard screws used for fastening, adjusting screws typically have a fine thread pitch to allow for small, incremental movements. Their primary function is to create a variable gap or position between two parts.

These screws are often employed in applications where precise alignment or tension is critical. Examples include optical instruments like telescopes and microscopes, where they are used to adjust focus or position lenses. In mechanical devices, they might be found in carburetors to regulate fuel-air mixture, or in sewing machines to control thread tension. They can also be used in certain types of clamps or vises to achieve a specific clamping force.

The design of an adjusting screw often features a knurled head or a slot for easy manual manipulation. Some may incorporate a locking mechanism, such as a jam nut, to prevent accidental changes to the setting once it has been precisely adjusted. The material used for adjusting screws can vary depending on the application, ranging from common steel to more specialized alloys for increased durability or corrosion resistance. The core principle remains the same: to provide a controllable and repeatable method for making small adjustments.
