ruuvinväännin

Ruuvi ruuvinväännin is a Finnish term that translates to "screw driver" in English. It refers to a tool used for turning screws. The most common type of ruuvinväännin is a manual tool with a handle and a shaft that ends in a tip designed to engage with the head of a screw. These tips come in various shapes and sizes to match different types of screw heads, such as flat-head (uraruuvinväännin), Phillips (ristipääruuvinväännin), and Torx (kuusiokoloruuvinväännin).

Electric ruuvinvääntimet are also widely used, offering increased speed and reduced effort, particularly for repetitive tasks or when dealing with tougher materials. These powered tools typically have a rechargeable battery and a chuck that accepts interchangeable bits corresponding to different screw head types. The operation involves applying torque to the screw to either insert it into a material or remove it. Proper selection of the ruuvinväännin tip is crucial to avoid damaging the screw head or the tool itself. In woodworking, construction, and general maintenance, the ruuvinväännin is an indispensable tool.
