ruuvipuristimella

Ruuvi puristimella is a Finnish term that translates to "screw clamp" or "screw vice" in English. It refers to a type of mechanical fastener or tool used to hold or secure objects together through the application of pressure. The core mechanism involves a screw thread that, when turned, causes a movable jaw to approach or recede from a fixed jaw, thereby exerting a clamping force.

These devices are widely employed across various industries and DIY applications. In woodworking, screw clamps are essential for holding pieces of wood together while glue dries, ensuring a strong and precise bond. They are also used in metalworking for similar purposes. In automotive repair, they might be used to hold parts in place during assembly or repair. Beyond these specialized fields, simpler versions of screw clamps are found in everyday household items and tools for general-purpose gripping and fastening.

The design of a ruuvi puristimella can vary significantly depending on its intended use. Some are small and handheld, designed for delicate tasks, while others are large and robust, capable of applying immense force. Common types include C-clamps, bar clamps, and F-clamps, each offering different configurations for clamping accessibility and pressure distribution. The materials used can range from cast iron and steel for durability to lighter alloys for portability. The effectiveness of a ruuvi puristimella relies on the mechanical advantage provided by the screw thread, allowing a relatively small input force to generate a significant output clamping force.
