vääntösekä

vääntösekä is a Finnish term that translates roughly to "torque wrench" or "torque multiplier" in English. It refers to a tool or a mechanical system designed to apply a precisely controlled amount of rotational force, known as torque, to a fastener such as a bolt or nut. This precision is crucial in many engineering and automotive applications where over-tightening or under-tightening can lead to component failure, leaks, or safety hazards.

There are two main types of vääntösekä. The first is a torque wrench, which is a hand tool that allows the user to set a desired torque value. When this value is reached, the wrench typically provides a tactile or audible click, or a visual indication, signaling that the correct torque has been applied. These are commonly used in automotive repair for tasks like wheel lug nuts and engine components.

The second type, a torque multiplier, is a more complex mechanical device that uses gears to increase the input torque. This is useful for situations where very high torque values are required, and applying them manually with a standard wrench would be impractical or impossible. Torque multipliers are often found in heavy machinery repair, industrial maintenance, and situations involving large bolts and nuts. The primary function of any vääntösekä is to ensure fasteners are tightened to their specified torque values, contributing to the overall integrity and safety of a mechanical assembly.
