Square drive impact wrenches

Square (nut runners)

— the “square” type cartridge has a corresponding shape and differs from other types in that the working tool during installation is not inserted into the recess in the cartridge, but is put on it from the outside. In addition to electric wrenches, this design is widely used in hand tools with interchangeable heads, and therefore in many wrenches with a “square” these heads can be used as working nozzles — the main thing is that the dimensions of the square match (today there are several of them).
