säätöruuvi

Säätöruuvi, which translates to "adjustment screw" in English, is a type of screw designed to allow for precise adjustments in mechanical systems. Unlike standard screws that are primarily used for fastening, säätöruuvi's thread pitch or head design is optimized for fine-tuning. These screws are commonly found in a variety of applications where minute changes in position, pressure, or tension are required.

The primary function of a säätöruuvi is to create or alter a mechanical connection incrementally. This can be achieved by turning the screw, which causes a controlled movement of a connected component. For example, in optical instruments, adjustment screws are used to focus lenses or align mirrors with great accuracy. In machinery, they might be used to set the gap between parts or to regulate the tension of a belt.

The design of a säätöruuvi often features a fine thread, meaning there are more threads per inch (or millimeter) compared to a standard screw. This fine threading allows for a smaller change in position for each rotation of the screw, facilitating precise control. Some säätöruuvi designs also incorporate features like knurled heads for easier manual turning or slotted heads for use with a screwdriver. The materials used can vary depending on the environment and load requirements, ranging from common metals like brass and steel to more specialized alloys.
