Ruuvi, often translated as "screw" in English, is a type of fastener characterized by a helical ridge known as a thread. This thread is designed to engage with a mating thread in a component or to create its own thread in a material when inserted. Screws are commonly used to fasten two or more objects together. The head of a screw typically features a drive type, such as a slot, Phillips, Torx, or hexagonal recess, which allows for a tool to be inserted to apply torque and rotate the screw. The body of the screw, between the head and the tip, is known as the shank and may be threaded along its entire length or partially. The tip of a screw can vary in shape, with common types including pointed, blunt, or self-tapping designs. Screws provide a removable fastening solution, meaning they can be tightened or loosened as needed. They are manufactured from a wide range of materials, including metals like steel, brass, and aluminum, as well as plastics, to suit various applications and environmental conditions. The selection of a screw depends on factors such as the required holding strength, the materials being joined, and the intended use.
