Ohjausruuvit

Ohjausruuvit, also known as steering screws or adjusting screws, are threaded fasteners used to make precise adjustments in mechanical systems. They are characterized by their fine threads, which allow for very small movements when the screw is rotated. This fine pitch is crucial for achieving the level of control required in many applications.

The primary function of an ohjausruuvi is to move one component relative to another with high accuracy. They are commonly found in optical instruments like telescopes and microscopes, where precise alignment of lenses and mirrors is essential for clear imaging. In machinery, they can be used to set the position of tools, adjust tension in belts or springs, or control the gap between moving parts.

The design of an ohjausruuvi typically involves a screw with a well-defined thread pitch and a head that allows for easy and controlled rotation, often with a knurled surface for grip or a slot for a screwdriver. The mating component usually contains a threaded hole or a nut. The precision of the adjustment depends not only on the thread pitch but also on the rigidity of the system and the absence of play or backlash. Materials used for ohjausruuvit vary depending on the application, but commonly include steel, brass, or stainless steel for durability and corrosion resistance. Their simple yet effective mechanism makes them a fundamental component in many precision engineering tasks.
