justeringsskruer

A "justeringsskrue," which translates to "adjustment screw" in English, is a type of threaded fastener primarily used for making precise adjustments to mechanical components or systems. Unlike standard screws used for assembly, adjustment screws are designed for fine-tuning rather than permanent fastening. Their threads are typically very fine, allowing for small, incremental movements when rotated.

These screws are commonly found in a wide range of applications. In optical instruments like microscopes and telescopes, they are used to focus the image. In musical instruments, adjustment screws can fine-tune the tension of strings or the alignment of parts. Within machinery, they might be employed to set clearances between components, control the position of a lever or arm, or adjust the tension of a spring.

The mechanism of an adjustment screw usually involves threading it into a fixed hole or nut. As the screw is turned, its head or an accessible feature moves in or out relative to the mounting surface, thereby altering the position of whatever it is in contact with. They can be made from various materials, including steel, brass, or stainless steel, depending on the required strength, corrosion resistance, and precision. The end of the screw may be flat, pointed, or ball-shaped to suit the specific application.
