ruuvivääntimen

A ruuvivääntimen, commonly known as a screw gun or screw driver in English, is a hand tool used for turning screws. It typically consists of a handle and a shaft with a tip that engages with the head of a screw. The design of the tip varies to match different types of screw heads, such as slotted, Phillips, Torx, or Pozidriv. The most common types are the slotted screwdriver, characterized by a flat, wedge-shaped tip, and the Phillips screwdriver, which has a cross-shaped tip designed to fit into a corresponding recess.

Manual ruuvivääntimet rely on the user's rotational force applied to the handle to drive the screw. For greater efficiency and power, powered versions, known as electric screwdrivers or screw guns, are widely used. These electric tools utilize a motor to rotate the shaft and tip, significantly reducing the effort and time required to insert or remove screws. They often feature adjustable torque settings to prevent overtightening or stripping of screw heads.

The choice of ruuvivääntimen depends on the type and size of the screw, as well as the material being fastened. Using the correct tip type and size is crucial to ensure a secure fit and prevent damage to both the screw head and the tool. Professional tradespeople and DIY enthusiasts alike rely on ruuvivääntimet for a vast array of tasks, from furniture assembly and electronic repairs to construction and automotive work.
