A ratchet spanner with a set of sockets is used to unscrew and tighten threaded joints with a hexagonal fixing element. Thanks to the ratchet, there is no need to take the spanner off the nut to make another turn, whilst the sockets allow for work with screws of various sizes. The 11-piece set makes it possible to get a full set of spanners in sizes 8 - 19 mm. The universal application of the spanner allows for its usage both in the workshop, as well as in renovation, construction and installation works.
