Ruuvauskalu

Ruuvauskalu, also known as a screw extractor or screw puller, is a tool used to remove screws that have become stripped or damaged, making them difficult to remove with conventional methods. It is commonly used in various fields such as automotive repair, woodworking, and general maintenance.

The tool consists of a handle and a tip with a series of teeth or prongs. The teeth are designed to grip the screw head and apply force to the threads, allowing the screw to be pulled out. The handle provides leverage, making it easier to apply the necessary force.

Ruuvauskalu is particularly useful when dealing with screws that have been over-tightened, have rusted, or have been damaged by corrosion. It can also be used to remove screws from tight spaces or hard-to-reach areas.

To use a ruuvauskalu, the tip is first inserted into the screw head. The handle is then rotated to engage the teeth with the screw threads. The tool is then pulled upwards or downwards, depending on the orientation of the screw, to extract it from the material.

Ruuvauskalu is a versatile tool that can save time and effort when dealing with stubborn screws. It is an essential tool for anyone involved in repair, maintenance, or construction work.
