ABSTRACT:
A slide stop device of a hexagonal spanner serves for preventing a rounded edged inner hexagonal screw to slide as the hexagonal spanner drives the inner hexagonal screw. The slide stop device comprises a spanner body; one end of the spanner body having a driving portion. The driving portion has at least one axial slot; a screw hole formed along an axial direction of driving portion; a through hole extending from an inner side of the screw hole and being at the same line with the screw hole; a screwing resisting element capable of being screwed into the screw hole; one end of the screwing resisting element having a driving hole so that an opening can be inserted into the cruciform hole to drive the screwing resisting element to rotate. In use, the screwing resisting element is inserted into the screw hole.
