16:

• The pliers according to claim 8, wherein the pliers are configured such that a round bolt (49) can be grasped by one or more oppositely arranged and oppositely oriented teeth (28) of the first and the second working surface (23, 24) in a front region (51) facing the free end (48) of the jaws (5, 6), as well as in a rear region (52) of the pliers mouth (7) facing the rotational axis (x), wherein teeth (28) of different groups (G1, G2, G3, G4, G5 and G6) of teeth (28) are respectively engaged with the round bolt (49) in the front and the rear region, wherein the round bolt can be grasped in the rear region by two teeth (28), which are respectively assigned to one of the opposite working surfaces (23, 24) and the tooth tips (29) of which extend in opposite directions, and wherein the round bolt likewise can be grasped in the front region (51) by two teeth (28), which are respectively assigned to one of the opposite working surfaces (23, 24) and the tooth tips (29) of which extend in opposite directions.

17:

• The pliers according to claim 16, wherein the pliers are configured such that twofold grasping of the round bolt (49) is possible if the round bolt (49) has a diameter (e) that requires a pliers mouth opening of approximately 10 degrees for the grasping of the round bolt (49) in the front region (51) or in the rear region (52).
