ruuviyhteys

Ruuviyhteys is a Finnish term that translates to "screw connection" or "threaded connection." It refers to any joint or assembly that uses a screw or bolt and a corresponding threaded hole or nut to fasten two or more components together. This is a fundamental and ubiquitous method of mechanical fastening used across a vast range of applications, from simple household repairs to complex industrial machinery and construction projects.

The principle behind a ruuviyhteys relies on the mechanical advantage provided by the inclined plane of the screw threads. When a screw is rotated, its threads engage with the threads in the receiving material or nut, converting rotational motion into linear motion. This action draws the components together, creating a secure and often very strong joint. The tightness and holding power of a ruuviyhteys can be adjusted by controlling the torque applied during tightening.

Variations of ruuviyhteys exist, differing in thread type, size, and material. Common thread forms include metric, imperial (unified thread), and specialized threads for specific industries. The materials used for screws, bolts, nuts, and the components being joined also vary widely, chosen based on factors such as strength requirements, environmental conditions (e.g., corrosion resistance), and cost. The reliability and ease of assembly and disassembly make ruuviyhteys a highly versatile and enduring fastening solution.
