Wrench (tool)

 

 

We recognize several types of keys according to their construction. The basic division is into outer and inner n-edges. Some keys consist of several interchangeable parts - they use a basic lever and a socket head of the appropriate size. Additional accessories are often supplied with the heads (extension rods, joints, flexible extensions, ratchets...). 12 mm Gola is most often used.

 

A wrench is a tool primarily designed for tightening and loosening (screwing) screws and nuts. The basic principle of any wrench is a lever (force concentrator). The shape of the key purposefully depends on the shape of the screw head (nut...).

The basic shape used in technical practice is the hexagon (hexagonal screw and nut) internal and external. Triangular, quadrilateral, octagonal (star) and dodecagonal (asterisk) are used less often.
