Wrenches are always in demand - one of the simplest and at the same time irreplaceable hand tools. In the usual version they are flat and consist of a connecting part and a work surface. They typically have an all-metal construction and are made from high-strength tool steel.
Simple devices are widely used, from household repairs to almost all areas of production. Such helpers are relevant wherever screw connections occur. Since the range of functions is limited to loosening and tightening screws, nuts and other parts, the range of applications is huge. From children's construction sets to a car to a space station, special tools are required to assemble and dismantle mechanisms of varying complexity.
